Arthur Negus Fuller (1879-1945) was the youngest son of artists George and Agnes (Higginson) Fuller of Deerfield, Massachusetts. In 1915, he began creating monotypes which are single prints pulled from designs painted on metal or glass. He expanded to intaglio printing around 1920. This method is the opposite of relief printing, where raised areas, such as on a woodcut, hold the ink.  Intaglio printing involves etching a design onto a copper plate, applying the ink, and then wiping it off so that the design is created by the ink in the inscribed areas.
