I've found a few old toy molds over time similar in construction to this one--described by the seller as a cat, but I think surely meant to be a kangaroo?--and find them quite evocative things, with these bolts and screws protruding on all sides, so always grab them when I see them. I especially like the pencil drawn eye on the wooden side of this guy. And how the ears could also read as an open beak tweeting at the sky. The mold side is still entirely filled with some sort of composite material. 

5 1/4" x 2 7/8" x 1" d. Very good condition, with some dryness to the wood. Stands up on its own and looks ready to hop along!
