This 5-cent Physical Fitness-Sokol commemorative postage stamp was first placed on sale through the Washington, DC, post office on February 15, 1965.
Norman Todhunter designed the stamp, inspired by the statue of a discus thrower that stands near the State Department in Washington, DC. It was issued to publicize the importance of physical fitness and for the centenary of the founding of the Sokol (athletic) organization in the United States.
This stamp was printed on the Giori press and issued in panes of fifty stamps each. An initial printing of 120 million stamps was authorized.
