New York World’s Fair (1939–1940) was an international exposition held in Flushing Meadows - Corona Park, Queens. Organized under the theme “Building the World of Tomorrow,” it brought together nations, corporations, architects, and artists to showcase visions of modernity, progress, and technological innovation. Despite unfolding on the eve of World War II, the fair attracted over 44 million visitors and left a lasting imprint on American design, urban planning, and popular imagination.
