This 1974 10¢ Tennis First Day Cover bears the U.S. postage stamp honoring the centennial of tennis in America, postmarked Forest Hills, NY on August 31, 1974.
The stamp commemorates 100 years since the first tennis courts were laid out in the United States in 1874. Forest Hills, home of the West Side Tennis Club, served as the longtime venue for the U.S. Open and remains one of the most iconic locations in American tennis history.
The cover features the colorful stamp design showing a stylized tennis racket and ball, with the dates 1874–1974 printed directly on the envelope as part of the official first-day cachet.
A fine addition for collectors of sports topicals, U.S. commemoratives, or postal history from the 1970s, this clean FDC displays well and captures a milestone in both philately and American sports.
