Besides doing a silkscreen poster series of my Día De Los Muertos Nintendo characters, I am also planning on making silkscreen postcards. I also decided to color them in a muted palette for fun. Here's what I have so far.
Link (Legend of Zelda)
King Hippo (Punch Out)
Mario (Super Mario Bros)
I am printing 6 postcards on a 12"x12" sheet of cardstock, so I have one more design to come up with. I might actually do a couple more designs, and pick three of the best. I have four heroes and one villain so far. I don't know if my set should be all heroes, or three heroes and three villains.
