The Century of Progress International Exposition, otherwise known as the 1933 Chicago World's Fair, was held along Lake Michigan and Northerly Island Park in Chicago, Illinois, from May 27, 1933, to October 31, 1934. The theme was "Science Finds, Industry Applies, Man Conforms." This small collection of photographs shows various views of the fair. The images are snapshots of buildings, exhibits, and amusements taken by an unknown photographer throughout the fairgrounds. The collection provides insight into what the experience of an average fairgoer was like.

World's Fairs or International Expositions are large-scale exhibitions highlighting technology, agriculture, and other innovations of national or cultural significance. The New York World's Fair occurred in Flushing Meadows, Queens, from April 30, 1939, to October 31, 1940. The theme was "The World of Tomorrow." This souvenir diary and photograph album combines official drawings and photographic images of buildings at the 1939 New York World's Fair with a personal photograph album and diary section, in which the reader was to record his or her own memories of the fair. The diarist who completed this souvenir remains unidentified.
