Why I Sign, Number, and Document Every Piece I Sell

Provenance is the boring word for the most important thing in an art sale: a paper trail proving the piece is what the artist says it is. Without it, you have a painting. With it, you have an asset that can be insured, valued, sold, donated, and inherited.

Here's what every original that leaves my studio gets, and why it matters more than people think.

A signature on the front

Every original is signed on the front, usually in the lower right corner, in a way that's part of the visual composition. Some pieces get a signature integrated into the artwork itself. Either way, it's there from completion. No piece leaves the studio without it.

A signature on the back

The back of the piece holds the second signature, the title, the year, and the medium. Front signatures fade or get covered by frames over decades. Back signatures stay readable as long as the canvas or wood does.

If you ever flip a piece over and find nothing on the back, that's a flag. Real working artists sign the back as a matter of habit.

A printed Certificate of Authenticity

Every shipped original arrives with a printed COA. The certificate has:

Title of the work. Year completed. Dimensions. Medium and substrate. A photograph of the piece. The artist's printed name and signature. A unique reference number that ties the certificate to the studio's record of that piece.

If the piece is a limited edition, the certificate also notes the edition number out of the total. Originals don't have edition numbers, but they do get a unique studio reference.

A digital backup

The buyer also receives a digital copy of the COA by email. If the printed certificate gets lost over the years, the digital copy can be reissued from studio records. The studio keeps a permanent record of every piece sold, including the buyer's contact details (with consent).

Photo documentation at delivery

Buyers receive photos of the piece taken in studio, plus photos taken sealed and labeled before shipping. If the piece arrives in a state that doesn't match those photos, there's a clear paper trail for the insurance claim.

Why the documentation outlasts the paint

A well-cared-for original can last centuries. The piece you buy today might be on a wall in 2150. The artist will not be around to vouch for it. The certificate, the studio records, and the paper trail of any resale are what tell the next collector that the piece is real.

This is also how art retains value. A piece without provenance is harder to sell, insure, or donate. A piece with clean documentation slides through every step. The cost of doing the documentation right is small. The cost of skipping it shows up only when you need it most.

What to ask any artist

Before buying, ask: "Does this come with a certificate of authenticity? What does it include? Can you show me a sample?"

A real working artist can answer that in one sentence and probably already photographed the certificate that's about to ship with the piece. If the answer is vague, that's the answer.

Provenance is the part of the sale you don't see on Instagram. It's also the part that proves the rest of the sale was real.
