An artistamp (a portmanteau of the words "artist" and "stamp") or '''artist's stamp''' is a postage stamp-like art form used to depict or commemorate any subject its creator chooses. Artistamps are a form of Cinderella stamps in that they are not valid for postage, but they differ from forgeries or bogus Illegal stamps in that typically the creator has no intent to defraud postal authorities or stamp collectors.
