This is a 1964 New York World's Fair 5¢ First Day Cover postmarked at the fairgrounds on April 22, 1964. The stamp depicts the iconic Unisphere against a red background, with the dates 1964–1965 and "New York World's Fair" inscribed above.
The 1964–1965 New York World's Fair was one of the largest international expositions of the postwar era, drawing over 50 million visitors to Flushing Meadows. It showcased American optimism, technological progress, and corporate innovation during the height of the Space Race and Cold War.
A notable detail is the clean, official-style "FIRST DAY OF ISSUE" imprint beneath the stamp, typical of early Artcraft or Artmaster productions for this issue. The circular World's Fair, N.Y. postmark is crisp and well-centered.
A solid addition for collectors of World's Fair topicals, mid-century expositions, or 1960s U.S. commemoratives, with fresh color and sharp cancellation.
