Two wind-up dancing dolls made in Germany, most likely by Sweetheart, fully working (tested), they dance round and round. There is a clockwork mechanism inside, a pin is sticking out of the back of the dolls, a key fits on to that so you can wind them up. Their costumes are from the Bavaria (Bayern) area in Germany. Both dolls are marked 'M.W. Germany' on the back of a leg. The dolls come without key!
