The 1930s saw an explosion of world’s fairs across Europe and the United States. In that decade alone there were fairs in multiple Belgian cities, as well as Paris, New York, San Francisco and, of course, Chicago. The Midwestern fair was famous for the “White City” that was built along the shore of Lake Michigan, with many of the architecturally advanced and beautiful buildings still standing today. Despite their promises of progress and peace, however, the fairs could not stave off the advance of fascism and resulting war. The exhibition, which opens Sept. 19 and runs through Jan. 5, 2014, includes posters, memorabilia and other objects collected from the various fairs.
