The 1939–1940 New York World's Fair transformed Flushing Meadows–Corona Park into a vision of "The World of Tomorrow." Spanning 1,202 acres, the fair welcomed more than 45 million visitors to explore futuristic architecture, technological innovations, cultural exhibits, and pavilions representing 62 nations, 35 U.S. states and territories, and over 1,400 organizations and companies.
The fair celebrated optimism and progress despite the outbreak of World War II just months later. Although it was not financially successful, the exposition left a lasting legacy, helping shape the development of Queens and influencing future world's fairs with its bold vision of modern life.
