1933 Chicago World's Fair - Firestone Automatic Curing Molds - IL:  A Century of Progress International Exposition, also known as the Chicago World's Fair, was a world's fair held in the city of Chicago, Illinois, United States, from 1933 to 1934. The fair, registered under the Bureau International des Expositions (BIE), celebrated the city's centennial. Designed largely in Art Deco style, the theme of the fair was technological innovation, and its motto was "Science Finds, Industry Applies, Man Conforms", trumpeting the message that science and American life were wedded.  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.  The beautiful modern Firestone plant and Exposition building on Lief Ericsen Drive, Twenty-third Street, features the complete manufacturing of automobile tires at the Exposition. Thousands of people have expressed a desire to see rubber and Tyre manufacturing as it is done in the Firestone plant, and so here they can see the same method and operations.  In the exhibition hall, interactive displays show, with the help of science and engineering development, the wonderful advances that have been made in automotive products and their service to motorists. There is a remarkable display relating to motor racing, including famous cars and trophies. Other interactive displays show the evolution of tires, batteries, spark plugs, brake linings, and other products manufactured by the company.  This Linen Era (1930-45) postcard, copyrighted in 1933, is in good condition.  R.
