paintings prints and stuff: linoprint fish and digital experiments- one easy print but with different colors in the background it gives more appeal. Maybe have them choose primary/secondary colors, warm/cool colors or different shades of one color.
Jacqueline in a Flowery Straw Hat, Picasso. 1964 It's so cool to actually see the linoleum Picasso carved to make this beautiful ink print. *correction, this is not a linocut, but a carved terra cotta tile with black slip.
