Against a teal midnight sky, the great steel Unisphere blazes over its mirrored reflecting pool — a 140-foot-tall promise of "Peace through Understanding" captured at the height of the 1964–1965 New York World's Fair in Flushing Meadows, Queens. The chrome-process color photograph catches every orbital ring and continental relief in metallic gold and blue, the structure's glow doubling in the 310-foot pool below while flanking observation towers stand sentinel among bare-branched trees. Promoted by United States Steel and designated the official symbol of the Fair, the Unisphere was the largest representation of Earth ever constructed — and for two summers it drew millions of optimistic visitors who arrived by monorail and left clutching souvenir postcards exactly like this one. The back identifies this as Official World's Fair Post Card WF-58, published by Dexter of West Nyack, N.Y., copyrighted 1961, 1962, and 1964 by the New York World's Fair 1964–1965 Corporation.
