This 2.50 zł stamp from Poland, issued in 1971, commemorates Lunochod-1, the first successful robotic lunar rover developed by the Soviet Union. The design depicts the rover traversing the Moon’s surface with Earth visible on the distant horizon — a striking symbol of early space exploration. The issue reflects Poland’s participation in celebrating humankind’s technological achievements during the height of the Space Age. This commemorative issue is highly prized by collectors of astronomy and Cold War–era philately.
