When someone wants to know who created your art, your signature tells them.
When someone sees your art for the first time and wants to know who the artist is so they can see more or learn more, your signature helps them find you.
Let's say someone buys a piece of art with an illegible signature for a hundred bucks at an artist's first show just because she likes it and can afford it (the artist, of course, is a complete unknown).
The buyer doesn't really follow the career of the artist and some years later because she's moving or her tastes have changed or whatever, she gives the art to an acquaintance who happens to like the way it looks.
People buy art all the time and forget who the artists are.
People sell, donate, transfer or otherwise give away art all the time without ever informing the new owners who the artists are (assuming they even remember), for instance, like when they move or downsize their residences, redecorate, have yard sales, or when they just plain get tired of looking at it.
If artists had any idea of the fates that befall unsigned works of art art or those with signatures that can't be identified, a lot fewer signatures would be deliberately incomprehensible or absent altogether.No matter what your signature looks like, what form it takes or where you put it, no work of your art is complete without one.Your signature identifies your art for all time as having been created, completed and approved of by you and you alone (with the exception of collaborative works, of course).The moral of the story is that you can sign your name as inscrutably as you want and wherever you want as long as you also clearly identify yourself as the artist somewhere, anywhere else on the art. Additional pointers for signing your art: * Art by artists who sign with initials, monograms, and symbols often meets similar fates to illegibly signed art.Here again no matter how in love you are with a cryptic or mysterious way of labeling, clearly sign or otherwise identify yourself elsewhere on the art.
