World's Fairs have captured the imagination of people from Seattle to Sydney for well over 150 years, and they continue to fascinate historians, architects, designers, and others. Chicago has hosted two World's fairs, and this digital collection from the University of Illinois-Chicago highlights publicity and other documentary photographs from the Century of Progress International Exposition. The Exposition was held in 1933 and 1935 along Chicago's lakefront, and there are over 1,400 items featured in this collection which document the spirit and exhibits of this remarkable event. The items here include demonstrations of Spanish bullfighting at the Exposition, a map of the grounds, photos from the General Electric "House of Magic", and views of many other buildings on the grounds. Visitors can search through the items at their leisure and they can also create their own collection via the "My Favorites" option.
