Falling in between the dark days of the Great Depression and World War II, the 1939-1940 New York World's Fair offered a refreshing prediction for "the World of Tomorrow."

There were exciting demonstrations of robot servants, computerized highways, color photography, and a new invention called television. Visitors could tour the latest in model homes, enjoy the marvel of air-conditioning, and watch the newest streamlined steam locomotive in action. America's largest corporations joined forces with nations from around the world to showcase the wonders of a future that was sure to come. There were also displays of past technical marvels, international culture and cuisine, and plenty of the innovative architecture that is a large part of these international expositions. Vintage photographs, most never published before, showcase what has been lauded as the most memorable world's fair of all time.
