Adding your signature to a painting not only identifies you as the artist, it's like adding a sign you're satisfied with the painting and no longer consider it a work in progress. How and where artists add their signatures is a matter of personal preference, and rarely stays the same throughout the artist's career. It's fascinating to see the styles and differences.
