Issued by the USSR in 1979 as part of the promotional series for the 1980 Moscow Summer Olympics, this vibrant semi-postal set showcases five Olympic sports in bold, sculptural style. The stamps feature Hockey (20+10k), Field Hockey (10+5k), Handball (16+6k), Basketball (6+3k), and Football (4+2k), each rendered in striking monochrome athlete figures symbolizing motion and strength. The “+” denominations indicate a surcharge supporting Olympic development funds, making them semi-postal issues. Prominently displaying the Moscow-80 Olympic emblem, this set reflects Soviet graphic design excellence and Cold War era Olympic history. A strong thematic addition for Olympic, Sports, or USSR collectors.
