Is This Autograph Real?

The checklist

The 12 autograph
checks

Work top to bottom. The early checks are about the shape and the physical act of writing and cost nothing but attention; the later ones are about the object, its history, and its paperwork. Any single clear failure is grounds to stop. Passing all twelve does not make an autograph authentic — it tells you the item is worth taking to a professional, and it tells you what to ask them.

What should I do with my item?Common questions
01check

Signature shape

Does the overall silhouette match the signer’s habit?

Look at it from a few feet away, then beside dated examples of the same person.

Genuine behaves like this

A signature has a shape its owner repeats for years — the same overall outline, the same rhythm of tall and short, the same amount of space it wants to occupy. Held at arm’s length, a genuine example looks like the person’s signature before you read a single letter.

A fake gives it away here

A copy usually gets the silhouette approximately right and the interior wrong, or reproduces one specific published example exactly. Shape is where forgeries look most convincing, which is why it is the first check and never the deciding one.

02check

Letter formation

Were the letters built in the signer’s order, or just made to look right?

Compare join by join against era-correct examples, not on overall shape.

Genuine behaves like this

Every signer builds each letter the same way — which loop closes first, which direction a capital is entered, whether the t-bar goes on before or after the next letter. This is the part of a signature the owner cannot easily change and a forger rarely notices.

A fake gives it away here

The outline matches but the joins are wrong: a stroke that should cross on top passes underneath, a loop closed counter-clockwise instead of clockwise, a t-bar floating free of the run of writing, letters assembled from separate pieces rather than written through.

03check

Slant of the writing axis

Does the writing lean the way this person leans?

Lay a straight edge along the letter stems and along the baseline.

Genuine behaves like this

Slant comes from how someone holds the pen and sits to the page, so it is remarkably stable across a career. Most signers keep their letters within a narrow band of angle, and the baseline runs at a habitual tilt.

A fake gives it away here

A traced or freehand copy often lands a few degrees off, because the forger’s own hand position fights the model. Watch for writing that leans one way while the baseline climbs another, or a slant that only matches on the first letter and then reverts to the copyist’s natural hand.

04check

Speed and flow of the signature

Was this written, or was it drawn?

Raking light across the surface, 10x loupe on the long descending strokes.

Genuine behaves like this

A signature is muscle memory. An adult has signed their name tens of thousands of times and executes it in roughly one to two seconds without watching the pen. That speed shows up as long, confident, tapering strokes, smooth curve transitions, and pressure that rises and falls in a rhythm — heavier on downstrokes, light out of loops.

A fake gives it away here

A forger is copying a picture, so the pen moves at drawing speed — five to fifteen times slower. Slow ink lays down a line of even width, curves flatten where the hand had to stop and re-aim, and the whole signature has no pressure story at all. Traced lines, autopens, and printed facsimiles are all monotone in exactly this way.

Specimen A — written
≈ 1.4 sec

A habit executed without looking at the pen.

  • entryPen already moving on contact — the lead-in tapers out of nothing.
  • weightLine thickens on downstrokes, thins out of loops. A pressure story.
  • exitLeaves the paper mid-air. One continuous pass, about 1.4 seconds.
Specimen B — drawn
≈ 11 sec

The same shape, copied by an eye instead of a hand.

  • terminalsBlunt ink deposits where the pen was set down and lifted.
  • tremorUniform width with a rope-like waver: drawing speed, not writing speed.
  • retouchA doubled line inside one stroke. Nobody corrects their own signature.
05check

Stops and starts

Was the pen already moving when it touched down, and did it stop where a hand would not?

10x loupe on the first and last 5mm, then on every stroke crossing.

Genuine behaves like this

Habitual signers land the pen in motion and take off in motion. Entry and exit strokes taper to nothing — a flying start and a flying finish, often a whip-thin tail that leaves the paper mid-air. Pen lifts happen between letter groups, at the same natural breaks every time.

A fake gives it away here

Copied signatures begin and end with blunt, rounded, ink-heavy terminals, because the pen was placed on the paper and then moved. Forgeries also stop where the model was hard to read — inside a letter, mid-curve, at a crossing — leaving a blot where the nib sat and a blunt restart a hair off the original line. Two overlapping lines inside one stroke is a retouch, and retouching is the single most common forgery tell.

06check

Tremors

Is there a shake in the line, and does it belong there?

10x loupe along the long curves; ask whether the tremor is even or selective.

Genuine behaves like this

Genuine tremor has a cause you can name: advanced age, illness, cold hands, a signature written standing up against a car roof or a stadium rail. It tends to run through the whole signature evenly and still travels at speed, with terminals that taper.

A fake gives it away here

Forger’s tremor is different — a fine, regular, rope-like wobble along the long curves, produced by a slow hand concentrating on a line. It appears in the difficult passages and disappears in the easy ones. A confident young signature that trembles only through its capitals was drawn, not signed.

07check

Slant consistency and proportion

Do the parts hold their relationship to one another?

Measure capital height, descender length, and word spacing; compare the ratios.

Genuine behaves like this

Within one hand, proportions stay put: capital height against lowercase, the length of a descender against the body of a letter, the width of a loop against its height, the spacing between the forename and surname. The slant holds the same angle from the first letter to the last.

A fake gives it away here

Copies drift. A forger working left to right gets the opening right and runs out of room or nerve — capitals a half-size large, a compressed or stretched surname, spacing that widens as confidence goes, a slant that steepens across the line. Measure the ratios rather than trusting the impression.

08check

Placement

Is it signed where this person, on this object, would have signed?

Look at the whole object before the signature; compare the inscription to the name.

Genuine behaves like this

People sign for legibility and convenience — on a light area of a photograph, clear of a face, at a size that suits the surface, angled the way a right-handed or left-handed signer naturally works. An inscription to a named recipient sits above the signature and shares its ink, slant, and speed.

A fake gives it away here

Forgeries turn up in places that flatter the fake rather than the signer: dead centre across a dark background, crammed into a margin, oddly small on a large photograph, or positioned to avoid the difficult part of the image. Watch for an inscription in a different hand, ink, or pressure from the signature it sits above, and for a signature that overlaps a printed facsimile or a previous owner’s marks.

09check

Ink and paper age

Could this pen and this paper have existed on the day it was supposedly signed?

Date the pen, then the paper or photographic stock, then the signature.

Genuine behaves like this

The writing instrument, the ink, the paper, and the photographic stock all agree with the claimed date, and the ink has aged the way the object has — sunk into the fibres, faded in step with the surface around it.

A fake gives it away here

Ballpoints did not reach American consumers until October 1945 and were not common for several years after. Felt-tip markers arrived in the 1960s; the Sharpie fine point launched in 1964. Resin-coated glossy photographic paper is largely a 1970s-and-later product. A 1930s studio portrait signed in Sharpie is finished before you look at a single stroke — and this one check kills more fakes than any other. Fresh, glossy ink on a genuinely old surface is the same warning in reverse.

Date the pen first

Instrument & stock chronology

Identify the writing instrument, then ask whether it existed on the claimed date. This single question retires more fakes than every stroke-level check combined, and it takes about ten seconds.

  1. 1884

    Practical fountain pen

    Lewis Waterman’s capillary-feed patent. Before this, dip pens and pencil.

  2. 1888

    First ballpoint patent

    John J. Loud patents a ball-tipped pen for marking leather. Never a writing product.

  3. 1938

    Bíró ballpoint

    László Bíró’s viscous-ink design — the mechanism every later ballpoint uses.

  4. Oct 1945

    Ballpoints reach US buyers

    The Reynolds Rocket goes on sale at Gimbels in New York. A ballpoint signature cannot predate this.

  5. 1950

    Bic Cristal

    Cheap, reliable ballpoints become ordinary. US launch follows at the end of the decade.

  6. 1963

    Fibre-tip pens

    The Pentel Sign Pen arrives — the soft, slightly spread line seen on 1960s signatures.

  7. 1964

    Sharpie fine point

    The marker on most modern autographs. On a 1930s studio still, the case is closed.

  8. 1970s

    Resin-coated photo paper

    Modern glossy RC stock becomes standard, and it feels and ages differently to fibre-based prints.

  9. 1984

    Gel pens

    The Sakura Gelly Roll. Opaque gel ink on a pre-1980s item is an anachronism.

10check

Comparison to known real exemplars

Am I comparing this to the right decade of the same person?

Assemble three to five dated exemplars, then compare habits rather than outlines.

Genuine behaves like this

Signatures evolve. Fame compresses them, repetition abbreviates them, and age or illness degrades them. A genuine 1978 signature should look like 1978, not like the full careful version from 1954. Build a set of three to five dated examples from within a few years of your item — illustrated auction archives, museum and library holdings, facsimiles in reference books.

A fake gives it away here

The most frequent amateur mistake is judging a late signature against an early example and rejecting something real. The second is accepting a forgery copied from the single most-published example of that signature — which is exactly the one forgers work from, and the one specialists recognise on sight.

11check

Provenance

Can anyone actually account for where this came from?

Ask for the chain of custody in writing before money moves.

Genuine behaves like this

A signing event with a date, a witness, a photograph of the moment, a ticket stub, a dated letter, an estate inventory, or a dealer who watched the pen touch the paper. Useful provenance names people, places, and dates that somebody else can confirm.

A fake gives it away here

"Bought at an estate sale," "from a private collection," and "my uncle worked in the industry" are stories, not provenance. Be wary of a history that exists only in the seller’s description, and of quantities no one person could plausibly have signed for a single owner. For modern signatures, an in-person proof photograph of the signing is worth more than any opinion.

12check

Certificates of authenticity

Is the certificate worth anything, and is the certificate itself real?

Verify the serial number or hologram with the issuing house before buying.

Genuine behaves like this

A letter that illustrates your actual item, names the person who formed the opinion, carries a serial number, and can be verified with the issuer today.

A fake gives it away here

Forgeries very often arrive with certificates — a generic card with a logo and no image costs a forger almost nothing to produce. Worse, certificates from respected houses get counterfeited and pasted onto fakes. A certificate is a record of someone’s opinion, never proof on its own, and it has to be verified at the source rather than admired.

Verify, don’t admire

Piece of the Past publishes its certificate structure — an illustrated letter with matching tamper-proof holograms above a price threshold, a hand-signed card below it — and states its own certificate is among the most counterfeited in the trade, which is exactly why serials get checked at the source.

After the twelve

Passing all twelve does not make it authentic

A clean run through the twelve tests is not a verdict. What it does is tell you whether the item is worth sending to a professional — and what to put in front of them when you get there. A secretarial signature, an autopen, and the work of a skilled forger can all pass every test on this page, because in each case a real hand or a real machine put real ink on the surface at speed.

So treat the result as a triage decision rather than a conclusion. Keep three lists — what passed, what failed, and what you could not judge — and hand all three to someone with an exemplar library. A clear failure early on saves you the fee; a clean pass is the point at which paying for an opinion starts to make sense.

Selling

Interested in selling your newly found items?

An attic find, an inherited album, a box from an estate sale — if you would rather move an item on than keep it, Piece of the Past has a page for sellers setting out what it buys and what it takes on consignment. Settle the authentication question first. What you can document about a signature is what sets its price, and an unexamined autograph sells for what an unexamined autograph is worth.

With the item in hand

What should I do with my autograph?

Six steps, in this order. The first two cost nothing and protect the item’s value whatever the outcome turns out to be.

  1. 01

    Photograph it properly

    Take clear, well-lit photographs of the autograph and of the entire item. Shoot one set square-on and close enough to fill the frame with the signature, then step back for the whole object, the reverse, and any labels, stamps, or mounts. Add one frame under raking light — a single lamp low and off to the side — because grooves and impressions vanish in flat light.

  2. 02

    Account for where it came from

    Look for provenance: receipts, invoices, consignment paperwork, letters, studio or gallery labels, framing tickets, estate inventories, and anything naming a previous owner. Write the chain down in order with dates. A gap is not proof of a forgery, but it is the part a seller should be able to fill in — and the part to ask about before money moves.

  3. 03

    Read the certificate, then set it aside

    Examine any Certificate of Authenticity: who issued it, whether it names the person who formed the opinion, whether it illustrates your actual item rather than a generic example, and whether its serial or hologram can be verified with the issuer today. A certificate alone does not prove an autograph is genuine. It records an opinion, and it is worth exactly what the accountability behind that opinion is worth.

  4. 04

    Compare with known authentic examples

    Assemble three to five signatures you can trust — illustrated auction archives, museum and library holdings, facsimiles in reference books — dated within a few years of your item. Compare construction and joins rather than overall shape: which loop closes first, which direction a capital is entered, whether the t-bar goes on before or after the next letter.

  5. 05

    Run the twelve warning signs on this page

    Work down the twelve signs above in order. The early ones cost nothing but attention and a loupe; the later ones need exemplars and paperwork. Note which pass, which fail, and which you simply could not judge. That third list matters as much as the other two — it is the honest state of the item, and it is what an authenticator will want to hear first. Treat the result as a decision about whether to pay for an opinion, not as the opinion itself.

  6. 06

    Have it examined if doubt remains

    If uncertainty remains after all of that — and with a competent forgery, a secretarial hand, or an autopen it often does — consider having the autograph examined by an experienced professional authenticator. Ask what the opinion covers, who signs it, what it costs, and what happens if the item is later shown to be wrong.

Still unsure?

Some autographs cannot be settled by appearance alone

Even after all twelve checks, some items stay open. Forgers can be skilled, genuine signatures vary a great deal, and provenance is rarely complete. Three failures in particular are close to invisible at a kitchen table: a secretarial signature written by a real person, an autopen, and the work of a known forger. When the value or importance of the item justifies it, an experienced professional examination is the sensible next step.

Common questions

Questions people ask before they pay

How can I tell if my autograph is real?
Judge how it was written before you judge how it looks. Genuine signing is fast muscle memory, so the line tapers, the pressure rises and falls, the pen lands and leaves in motion, and the letters are built in the signer’s fixed order. Then check the medium against the claimed date, compare with dated exemplars of the same person, and look at the item’s history and paperwork. No single sign proves an autograph genuine, and neither does passing all twelve. A clean pass tells you the item is worth sending to a professional; one clear physical failure is enough to stop.
Does a Certificate of Authenticity mean an autograph is genuine?
No. A certificate is a record of somebody’s opinion, and anyone with a printer can produce one. What gives it weight is the issuer: a named examiner, a documented track record, an image of your actual item, a serial number you can verify at the source, and a stated policy on what happens if the opinion turns out to be wrong. Treat an unverifiable certificate as no certificate at all, and never let one override what the signature itself is telling you.
What is an autopen signature?
An autopen is a machine that holds an ordinary pen and traces a fixed template of a signature, so every copy is real ink on real paper. Presidents, astronauts, senators, and studios have used them since the mid-twentieth century for correspondence. Because the template never changes, autopen signatures are dimensionally identical to one another, carry no pressure variation, and stop dead at both ends. They are identified by matching the pattern, not by the quality of the ink.
Can a genuine autograph look different from another genuine example?
Yes, and this is where sound items get rejected by amateurs. Signatures evolve across a life: fame compresses them, repetition abbreviates them, and age, injury, or illness degrade them. A signature from 1978 should resemble 1978, not the careful full version from 1954. Sign-while-walking conditions, an awkward surface, or a felt tip on gloss all change the result too. Compare within a few years of the claimed date, and compare habits rather than outlines.
Can an autograph be authenticated from a photo?
Good photographs rule many items out — anachronistic ink, halftone printing, tremor, blunt terminals, and autopen matches are often visible in a sharp, well-lit image. Confirming that something is genuine is harder from photographs alone, because pressure, indentation, ink bleed into the surface, and the condition of the substrate are best read with the item in hand. In practice most examiners will give a preliminary view from images and say plainly when they need the original.
When should I use a professional authenticator?
When the value or importance of the item justifies the cost, when you intend to sell, insure, or gift it, or when the twelve signs on this page leave you genuinely undecided. Three failures are effectively invisible at a kitchen table: a secretarial signature written by a real person, an autopen, and the work of a known forger whose hand is recognised only by people who have seen thousands of examples. Each of those needs an exemplar library and someone who uses one daily.
