Chicago - Calder's Flamingo - 1986

Flamingo, created by American artist Alexander Calder, is a 16 m tall sculpture located in the Federal Plaza in front of the Kluczynski Federal Building. Calder's signature on the sculpture indicates it was constructed in 1973. Flamingo weighs 50 tons, is composed of steel, and is "vermilion" in color. The structure is a prominent example of the "constructivist movement", first popularized in Russia in the early 20th century.
