The Unisphere looms in gleaming steel against a powder-blue sky while the soaring bronze figure of "The Rocket Thrower" — sculptor Donald's masterwork — lunges skyward from its pedestal beside the Plaza of the Astronauts at the New York World's Fair of 1964–65, a fair that welcomed over 51 million visitors across its two seasons and etched the optimism of the Space Age into American memory. This official chrome card (catalog WF-3) was published by Dexter Press of West Nyack, NY — the preeminent publisher of chrome-era postcards in America — under official license from the 1964–1965 New York World's Fair Corporation, making it a primary souvenir artifact of the fair. The reverse carries a detailed description of the Unisphere: 140 feet tall, 120 feet in diameter, sponsored by United States Steel, symbolizing "Peace through Understanding." The front checklist card (PC-04862_01) doubles as a pavilion visit tracker, listing states from Alaska to Wisconsin plus federal and New York City exhibits — a charming period artifact of how families documented their fair experience. Both cards are unused and crisp.
