Border drawn around image in gray ink. The following two drawn ele-ments create a trompe l’oeilmat and trompe l’oeilmarbleized wood frame: (1) on paper: a second border inbrown ink with gray wash along top and left edge (creating a shadow on the illusionary mat); (2) on carton: a13/16” border in brown ink and white gouache with gray wash along bottom and right edge (which collective-ly create illusion of marbleized frame and its shadow). Verso of carton, inscribed in graphite at bottom cen-ter: Bonaventura Genelli
