The Century of Progress International Exposition 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 collection consists of two items from the Exposition. One item is a folded card containing five sets of sewing needles and a threader. The second item is a set of eleven souvenir cards from Ripley's Believe It Or Not Odditorium, with the original envelope and booklet.
