Issued by Poland, this striking 1970 stamp commemorates the historic Luna 16 mission, the first robotic probe to successfully return lunar soil samples to Earth. The dramatic artwork shows the Soviet automatic station descending toward the Moon against a cosmic sky, capturing the excitement of early space exploration. Printed by PWPW with rich photogravure detail and deep contrast tones, it is a classic Cold-War era space thematic. Highly sought after by collectors of space, astronomy, and Interkosmos-related issues. A strong addition to any Poland or worldwide science/technology collection.
