work to unemployed artists. Many were given the task of decorating government buildings, hospitals and schools. There was no specific art deco style used in the murals; artists engaged to paint murals in government buildings came from many different schools, from American regionalism to social realism; they included Reginald Marsh, Rockwell Kent and the Mexican painter Diego Rivera. The murals were Art Deco because they were all decorative and related to the activities in the building or city where they were painted: Reginald Marsh and Rockwell Kent both decorated U.S. postal buildings, and showed postal employees at work while Diego Rivera depicted automobile factory workers for the Detroit Institute of Arts. Diego Rivera's mural Man at the Crossroads (1933) for 30 Rockefeller Plaza featured an unauthorized portrait of Lenin. When Rivera refused to remove Lenin, the painting was destroyed and a new mural was painted by the Spanish artist Josep Maria Sert. Sculpture Monumental and public sculpture Sculpture was a very common and integral feature of Art Deco architecture. In France, allegorical bas-reliefs representing dance and music by Antoine Bourdelle decorated the earliest Art Deco landmark in Paris, the Théâtre des Champs-Élysées, in 1912. The 1925 Exposition had major sculptural works placed around the site, pavilions were decorated with sculptural friezes, and several pavilions devoted to smaller studio sculpture. In the 1930s, a large group of prominent sculptors made works for the 1937 Exposition Internationale des Arts et Techniques dans la Vie Moderne at Chaillot. Alfred Janniot made the relief sculptures on the façade of the Palais de Tokyo. The Musée d'Art Moderne de la Ville de Paris, and the esplanade in front of the Palais de Chaillot, facing the Eiffel Tower, was crowded with new statuary by Charles Malfray, Henry Arnold, and many others. Public art deco sculpture was almost always representational, usually of heroic or allegorical figures related to the purpose of the building or room. The themes were usually selected by the patrons, not the artist. Abstract sculpture for decoration was extremely rare. In the United States, the most prominent Art Deco sculptor for public art was Paul Manship, who updated classical and mythological subjects and themes in an Art Deco style. His most famous work was the statue of Prometheus at Rockefeller Center in New York City, a 20th-century adaptation of a classical subject. Other important works for Rockefeller Center were made by Lee Lawrie, including
