In 1926, after a stint spent making toys at the request of a Serbian toy merchant in Paris, Calder began creating his "Cirque Calder", a miniature, movable circus that uses movable wire models of various circus performers, like sword eaters and lion tamers. After this, Calder created complete pieces only using wire and in 1927 had a show of wire sculptures at the Weyhe Gallery in New York City. In 1930, he had a solo show of wire sculptures in Paris, at Galerie Billiet.
