In DTLA at the end of 2022:

Unsigned is a conceptual collaborative action that directly responds to a finding by Dr. Helen Gorrill, researcher and author of Women Can’t Paint, that the addition of a signature by a woman on an artwork devalues it to the extent that “female artists are more likely to leave their work unsigned.” Unsigned is a collection of “100 signatures from women and non-binary artists created to reverse the current negative value of the signatures through their transformation into artworks themselves.”

It's the brainchild of a brilliant conceptual artist Duo named Operator and Anika Meier.. The signatures were gathered, minted and sold.  Curated by Operator and Anika Meier
