Best Old Painted Face on Post with Excellent Patina and Unknown Function (Carnival?)

I have no real idea what function this once served--maybe some sort of a carnival knock down? Whatever the case, it has seen some knocking around, adding up to a perfect patina on that marvelous painted face, which in no world could I resist. Just an excellent thing with just the best old painted surface.

11" t x 3 1/4" w (face is 3 1/4" in diameter) x 2" deep. Perfect patina, structurally super sturdy and sound, with a loop on reverse for hanging.
