Century of Progress stamp FDC postmark May 25, 1933 (Chicago, IL)

A Century of Progress International Exposition was the name of a World's Fair held in Chicago, Illinois from 1933 to 1934 to celebrate the city's centennial. The theme of the fair was technological innovation. Its motto was "Science Finds, Industry Applies, Man Conforms" and its architectural symbol was the Sky Ride, a transporter bridge perpendicular to the shore on which one could ride from one side of the fair to the other.

A Century of Progress was organized as an Illinois not-for-profit corporation in January, 1928 for the purpose of planning and hosting a World's Fair in Chicago in 1934. The site selected was the land and water areas under the jurisdiction of South Park commissioners lying along and adjacent to the shore of Lake Michigan, between 12th and 39th streets. Held on a 427 acre (1.7 km²) plot of land in Burnham Park, much of which was landfill, and bordering Lake Michigan, the Century of Progress opened on May 27, 1933
