This 50 kopeks dark blue Soviet Union postage stamp depicts two youthful pioneers—a boy and a girl—symbolizing the vigor and optimism of Soviet youth. At the center lies the emblem of the GTO program (“Готов к труду и обороне” — Gotov k trudu i oborone, meaning “Ready for Labour and Defence”), featuring a running athlete over a star and hammer-and-sickle motif. The design promotes physical fitness, patriotism, and preparedness as national virtues during the late 1930s. Issued by the USSR Post, this classic stamp reflects socialist realism and the emphasis on collective youth training and civic responsibility.
