Egyptian Revival Beltbuckle Pharoah Metal Disc Cameo on Green Bakelite?

This is a very unusual Art Deco Beltbuckle. It has a brass disc with a pharaohs head attached to what appears to be bakelite. The buckle is 1 1/2" in diameter and is in very good vintage condition. It doesn't have the other side with the clasp but is usable just as is. It has two eye pins on the back side to sew onto your belt material and any hook would do.
