The size is continental standard 6" x 4", published by the Ministry of Communications of the USSR, circulation 50,000, quite small by Soviet standards. The special-edition commemorative stamp is canceled with the First Day cancel issued by the Moscow Post Office and dated 16 August 1978. The name of the artist, K. Petrov-Vodkin, is printed in the lower left-hand corner on the verso. The artwork presents perhaps his most famous and iconic 1912 painting Bathing of a Red Horse, blasphemous for the Russian Orthodox Church but praised by revolutionaries as a symbol of the coming social changes. The painting is exhibited in the State Tretyakov Gallery in Moscow.

In excellent, near-mint condition, showing just a tiny bit of storage wear to the verso.

Kuzma Petrov-Vodkin (Кузьма Сергеевич Петров-Водкин, 1878 - 1939) was a renowned Russian and Soviet painter. He painted in the style of avant-garde but the "revolutionary" content of many of his works earned him recognition and high praise of the Soviet ideologues despite avant-garde being a far step away from Socialist Realism, the official style of Soviet art.
