Wind Up Tin Hopping Rabbit with Baby, Japan. Very cute. Excellent condition, and she does work - kind of. She starts to hop when fully wound, but the spring is not strong enough to keep her going. Perhaps some oil would help. Regardless, it's a nice toy. Height is 4 1/2 inches. Made by Mikuni in Japan.
