How big is it?
The piece is 7 1/2 in. tall by 3 1/2 in. wide, and the medium is called 'Super Sculpey'. It's what a lot of people use to make those maquette statues of super heroes and comic book characters. It is backed by just under a half inch of hardwood sanded to match the contours of the sculpture itself. I'll have more pics up later tonight.
