The size is standard 6 ¼" x 4 ½", postally unused, published by the Ministry of Communications of the USSR, circulation unknown. The special-issue postal stamp features a profile portrait of Yuri Gagarin and the Cosmonaut Yuri Gagarin scientific vessel in tribute to the flight control teams. The stamp is canceled with a First Day cancel issued by Zvezdnyy Gorodok ("Star City") Post Office and dated 12 April 1980. The artist's name, Yu. Levinovskiy, is printed on the bottom flap on the verso.

In excellent condition.

12 April is celebrated as Cosmonautics Day in the (former) Soviet Union and some other post-Soviet states. In 2011 however, the UN General Assembly declared it as the International Day of Human Space Flight. Note however, that the lettering "Worldwide Day of Aviation and Cosmonautics" under the graphics on the left panel of the obverse was made in 1980, 31 years before the day became officially international.
