"Erotic Drawings" is a catchall series for works on paper that use lube as a medium. The lube, which can be different types including oil or silicone based, stains the paper and can thus be used as a vehicle for pigments, or deployed in combination with water-based materials to create a repel/attract technique. The works originate loosely in the amazing work of David Hammons. See also the sculptural series Libidinal Economy.
