A painter's mark is often a unique signature, monogram, or symbol that an artist places on their work. Sometimes, the painter methodically leaves mark to identify it as his/her own. Other times, it reflects a mood, a state of mind, or reflects the essence of what is painted. It can vary widely in form, from a full name elegantly written, to initials, to a distinct emblem or motif. Historically, painter's marks were not just identifiers but also an assertion of authenticity, ownership, and sometimes even an indication of the artist’s workshop or guild affiliation.
