Soybean Field outside the Ford Exhibition Building, Century of Progress International Exposition, Chicago, Illinois, 1934

Chicago's 1933-34 Century of Progress Exposition used the theme of progress to encourage optimism during the Depression. The 11-acre Ford Motor Company exhibit became the most talked-about exhibit of 1934, featuring a central Rotunda designed to simulate graduated clusters of gears. After the fair, this building became an attraction at Ford headquarters in Dearborn, Michigan, until it burned down in 1962.
