The size is 6 ½" x 4 ½", with a pre-printed special-issue commemorative postal stamp. Postally unused, published by the Ministry of Communications of the USSR, circulation unknown. The 1979 expedition took place from 16 March to 31 May, when a group of people reached the North Pole on skis, raised the Soviet flag and left a sealed container with different objects inside symbolizing the peaceful nature of the labor of the Soviet people. This expedition was the culmination of seven years of preparation and smaller-scale expeditions testing the possibility and feasibility of such a difficult and dangerous endeavor.

In excellent condition.
