“… I had embellished a humpty-dumpty circus made by a Philadelphia toy company. There was an elephant and a mule. They could be made to stand on their hind quarters, front quarters, or heads. Then there were clowns with slots in their feet and claws in their hands; they could balance on a ladder on one foot or one hand. I had once articulated these things with strings, so the clown would end up on the back of the elephant.”
– Alexander Calder, An Autobiography with Pictures (1966)
