Curt Valentin publishes Three Young Rats and Other Rhymes, with eighty-five drawings by Calder and edited by Sweeney.
In 1937, Calder completed Devil Fish, his first stabile enlarged from a model. He received two important commissions: Mercury Fountain (1937) and Lobster Trap and Fish Tail (1939). His first retrospective was held in 1938 at the George Walter Vincent Smith Gallery in Springfield, Massachusetts, followed by another in 1943 at the Museum of Modern Art in New York.
