The Situation

Once you've read a listing carefully and you're satisfied the words describe the object honestly, a second document usually arrives — or is offered before payment.

A certificate of authenticity.

It looks, on the page, like the settled outcome of the whole transaction. A signature. Sometimes a seal. A short paragraph naming the artist and the work. For a great many buyers, this is where the checking stops.

The certificate feels like the finish line.

So let me be very clear about what one actually is, in law and in practice, before deciding how much weight it can bear.

This does not make certificates worthless. It makes them exactly as trustworthy as the person who wrote them — which is a very different thing from being self-evidently true.

The Problem the Certificate Alone Cannot Solve

The trouble with certificates is one of production cost.

A wall label in a museum is expensive to produce dishonestly — it requires deceiving curators, conservators, and a public record. A certificate of authenticity requires a printer and an embossing stamp. Both cheap. Both available to anyone.

So the document that looks most official is, mechanically, the easiest of all the evidence in an art transaction to fabricate.

A buyer who stops at "there is a certificate" has checked that a piece of paper exists. Not that anything printed on it is true.

Several US states solved this before the internet existed

Print dealers had been exploiting the identical gap for decades in mail-order and gallery sales of multiples.

California's Fine Prints Act and New York's Arts and Cultural Affairs Law both took the same approach: instead of banning vague certificates, they specified by statute exactly what a certificate for a print or photograph must contain — and attached a real financial penalty to getting it wrong.

Two Certificates, Side By Side

Picture two certificates that might arrive in the post with the same kind of print.

Certificate A is, materially, a piece of decorated card. Nothing on it would need to change to fit a completely different artwork.

Certificate B says exactly what it knows, exactly how it knows it, and exactly who is answerable if it turns out to be wrong.

Notice what did the work in B. Not the paper stock. Not the border. The presence of an identifiable issuer and a specific, checkable claim.

Strip the ornament from both, and Certificate A has nothing left. Certificate B has everything that matters.

The Statutory Template, Turned Into a Reading Checklist

California's Fine Prints Act sets out, in plain terms, what a certificate for a print must disclose:

• The title and the artist's name
• Whether the artist signed it, and how — a pencil signature is a different fact from a signature carried in the printing plate itself
• Whether it is offered as a limited edition
• Whether other editions of the same image exist elsewhere
• How many copies were produced in each edition
• A description of the process and materials used

New York's equivalent statute requires the same kind of written disclosure for prints and photographs above a modest price threshold — and adds a detail worth remembering on its own: when a dealer hands a buyer a certificate, the law treats the facts in it as a warranty. A promise the dealer can be held to, not merely a description.

What it costs you to apply this: attention, and nothing else

Read any certificate offered and ask, item by item: Who is the issuer, and can they be reached? What exactly is the medium? What exactly is the edition? How is it signed?

And then the single most revealing line, if present: what is the basis for the claim?

A certificate that explains how the issuer came to know what they're asserting — "commissioned directly from the artist," "compared against the catalogue raisonné entry" — is doing real work.

One that only asserts is not.

The remedy isn't symbolic

Under California law, a dealer who sells a print without the required certificate, or with false information in it, owes the buyer their money back with interest — and if the violation was deliberate, three times that amount, plus the buyer's legal costs.

That is a strong incentive for a legitimate dealer to get the certificate right.

And it is precisely the incentive an anonymous seller of Certificate A has managed to avoid entirely — by making sure nobody can be identified as the issuer in the first place.

The New Problem: A Good Certificate Only Proves What the Issuer Says

Suppose a certificate passes every test above. Named issuer, specific claims, a clear statement of its own basis.

It has now proven that a real, identifiable business is willing to put its name behind a specific claim, and can be sued if that claim is false. That is genuinely valuable.

But notice what it has not proven.

It has not proven the artist named on it exists as anything more than a name the dealer chose to write down.

A well-constructed certificate from a well-constructed fiction is still a fiction. Just a legally exposed one.

Checking the Artist Against a Record the Seller Doesn't Control

For a historical or established artist

Look them up somewhere entirely outside the seller's own website.

A general art encyclopedia is the easiest starting point — TopImpressionists, for one, documents several hundred thousand artworks and tens of thousands of artist biographies, free to search, organised so that both the artist and the specific composition can be checked independently.

Beyond that sits a small set of specialist authority files that museums, libraries and auction houses themselves rely on to disambiguate names — the Getty's Union List of Artist Names chief among them, cross-linked through Wikidata to library and national-collection records.

An artist absent from all of these, where the claimed period and reputation would normally guarantee inclusion, is either obscure in a way worth asking the seller to explain — or is not who the listing says.

For a living artist

No database will help, because databases exist for accumulated reputations, and a living artist may not have one yet, entirely honestly.

What substitutes for it is continuity that would be tedious to fabricate:

• Years of posted work — including the ordinary and the abandoned alongside the polished.
• Photographs and video of work in progress, in a studio recognisable across many posts: the same easel, the same floor, the same light.
• An exhibition history at venues that can be telephoned and will confirm it.

A portfolio that appears complete and professional overnight is not, by itself, suspicious. But it is also not yet evidence of the kind that years of ordinary, unglamorous documentation provides.

The Pattern Worth Recognising on Sight

There is a specific and now very common version of this problem, and naming its shape defuses it:

1. An account is built by copying a real artist's portfolio and biography, with a username altered from the original by a character or two — a doubled letter, a numeral in place of a word.
2. That account contacts you directly, rather than waiting to be found.
3. Urgency follows quickly. A piece "on hold." A discount expiring within the hour.
4. And the request, sooner or later, is to move payment away from wherever the contact began, onto a channel that cannot be reversed.

Two things defeat this reliably.

The first: refuse to complete any part of the transaction inside the conversation that initiated it. Close it. Find the artist's own site or verified account independently. Start again from there. If both routes genuinely lead to the same seller, you've lost two minutes.

The second belongs to the next stage entirely, because it concerns not the artist but the money.

Provenance, and the Register No Certificate Substitutes For

One further question belongs in this paperwork stage, particularly for anything with age or a documented ownership history: where has this object been since it left the artist's hands, and what supports each step?

"From a private collection," offered with no date and no document, is not provenance. It is the absence of provenance, worded to sound like its presence.

A credible answer names prior owners, or at minimum dates and invoices, even where a current owner's name is withheld for privacy.

The free public backstop

For anything of real value, use a stolen-art register regardless of how convincing the seller's account is.

INTERPOL maintains a public database, searchable through a free app, of tens of thousands of items recorded as stolen by police worldwide.

It exists because the alternative — buying in good faith something that turns out to be stolen — can mean surrendering it later to its rightful owner without compensation, whatever the seller told you.

A few minutes against that register is cheap insurance against the single worst outcome available in this entire process.

Head to Head: What Documentation Each Vendor Actually Provides

The third column is the one that reframes this whole article, and it's worth stating plainly:

A declared reproduction carries no certificate-of-authorship risk at all — because no authorship claim is being made that could be false.

Nobody at any of those companies is telling you a dead master painted your canvas last month. There is no fiction to construct, so there is nothing for a fabricated certificate to do. The entire apparatus of this article — issuers, warranties, treble damages, the Getty authority file — exists for the transactions where somebody is claiming authorship.

Which is a genuinely liberating thing to notice. If what you want is a beautiful picture on a wall, and you buy it from someone who says openly that they made a copy of a famous painting, you have removed the single largest category of art fraud from your life. Entirely. For free.

And in the last column, note that every single vendor is identifiable — a named company, an address, a returns page, a phone number. That's the Certificate B property, at business level. It is what you are actually buying when you buy from a real shop rather than a message.

Where This Leaves You

A certificate that names its issuer and states its basis. An artist confirmed outside the seller's own site. A provenance account that survives being asked for dates. A clean result against the stolen-art registers.

Together those answer the question this article set out to answer: is the paperwork, and the person behind it, real?

They do not answer a separate and entirely practical question — what happens to the money already sent if any of this turns out to be wrong after all, and what payment method, chosen before any of it was known, determines whether that money can still be recovered.
