Issued in 1971 to commemorate ten years since mankind entered the space age, this striking 10 kopeck stamp honors Yuri Gagarin and the dawn of human spaceflight. The design features Gagarin’s iconic helmet portrait alongside a stylized Sputnik satellite, symbolizing Soviet leadership in early space exploration. Printed in rich brown, red, and blue tones, the engraving-style artwork gives the issue strong visual depth and classic Soviet aesthetics. The Cyrillic inscription reads “10 Years of the Cosmic Era – First Human Flight into Space.” A key thematic piece for space, Cold War, and technology collections.
