Such a fun one. This is a game counter for bridge or whist, with the eyes and mouth of the monkey changing as one advances (by turning the dials) points and games and the trump suit on reverse. Clearly made as an advertising card for the Burrough Adding Machine, sold by Frank Spiekerman in Philadelphia, c. 1900 or so. I can't find another like it out there. Don't monkey with the score--but a great monkey face to monkey with!
3 1/8" x 2 3/8" and in great condition. Made of celluloid--and flat, like a business card.
