Discovery and Identify...

The Artists' Signatures Discovery EngineSM was designed from the ground up to help searchers easily determine the identity of artists with illegible or difficult to read signatures by enabling you to search based on the way the signature appears on a work of art.  Every illegible signature, monogram, and symbol in our comprehensive database of over 100,000 examples was manually reviewed by our team to ensure that each signature can be identified by our users based on the mark's appearance alone.

Every artist profile contains biographical reference information including, birth and death dates (if available) from hundreds of reputable sources.
