Two recent events triggered this sidebar question: “When did artists begin signing their artworks?” One is my reading of The Art Forger, an entertaining thriller given to me over the holidays.
The other is a news item about a group of artists filing a class action lawsuit in California on Friday, January 13, 2023, against the text-to-image generators Stable Diffusion and Midjourney for copyright infringement. The fact that artificial intelligence is being used to outright copy or render paintings in an artist’s style is unnerving.

When Did Artists Begin Signing Their Artworks?
The short answer: During the early Renaissance, that is, the 15th century. Artist signatures became prevalent as art production shifted from guild systems to individual artists. A signature was a means of differentiating one’s talents from those of lesser peers. The cultural climate was ripe for this shift as the combined influences of an increased awareness of nature, a revival of classical learning, and a more individualist view of man took hold.
My art history brain kicks in. Were there more reasons for signing artwork? How did artists sign their work? I discovered some answers that made me regard my artist’s signature from a new perspective.
Reasons for Signing the Artwork.
A signature is a unique extension of the artist. An artist’s signature is like a calling card, the one consistent element given to each piece an artist creates. Signing a painting claims ownership and authentication, giving it additional value and marking it as a complete, sellable piece.
Signatures can be part of the artistic process. When an artist signs their work, it can be a note-to-self that the piece is complete and the artist has declared it so; therefore is no need to rework or retouch any part of it.
Signature with Notes.
We typically think of artists’ signatures appearing in the lower right of a painting. However, some artists used their signatures as an extension for record-keeping. Artists have used the backside of paper and canvases to not just sign their name but to include the time, place, medium, dedication (especially if it is a portrait), title, and list of colors used to paint the piece.
Ways Artists Used Their Signatures.
There is no shortage of ways an artist might use their signature. Artist and renowned expert John Castagno produced 17 reference books cataloging artist signatures throughout history. For museums, galleries, and collectors, an artist’s signature is a way to date artwork. One of the more unusual signatures is that of James McNeill Whistler, who used a butterfly motif not only for his art but in personal correspondence.


Of course, some artists’ signatures become as famous as the artists themselves. Albrecht Dürer’s famed monogram is seen prominently on everything he created, from printed masterpieces to quick sketches. His “AD” trademark was so admired and popular that Dürer went to court in both Nuremberg and Venice in a successful bid to protect his authorship. Perhaps this is the first notable case of an artist’s copyright.
There were conditions when a fake artist’s signature could be used for good intentions. Works by Jewish artists doctored their signatures to non-Jewish names so that their work would not be destroyed by the Nazis during World War II.
Contemporary artists have equally varied reasons and ways of signing their work. I love it when an artist works their signature into the composition instead of opting for the classic lower-right placement. Artists will sign their work on the front, others sign on the back, and some do not sign their work at all. Other artists, like street artist Banksy, are so famous that they no longer sign their work. To sign or not to sign is the artist’s personal statement.
My Artist’s Signature.
My own artist’s signature is a monogram that began to emerge right around the time I started drawing. I use the block letter K (for Kristin) in the hand-drawn block letter style my father used when I was growing up. Later, I added the double circle to give it a symmetrical, symbolic feel. I drew this monogram signature on finished watercolors with a No. 2 pencil. Not all were successful, and rather than feeling like I spoiled the painting with a botched circled K, I standardized it by digitally rendering it.




I use the digital format to sign scanned images I post online, as in the examples shown above. It’s the same digital signature you’ll find in the corner of every print in my shop — a small thread running from a No. 2 pencil mark to whatever ends up on someone’s wall.
Then I declare the piece finished. But not complete. The work has to be seen and experienced by others for the art to feel complete.
Parting Thoughts On Artist Signatures.
There were moments when I thought I would change my artist’s signature and move away from the double circle K. Then I had to ask myself why get rid of something with history, ties to my father (who is also a practicing artist and art historian), and is uniquely me. Right.
POSTSCRIPT: I have begun adding a little bird silhouette in my watercolor paintings as an alternative signature on the front side of my pieces. The little bird has personal significance to me. The circle-K signature is reserved for the back sides of paintings and drawings, and on digital versions of my work.
