Почта СССР (Post of the USSR) issued in October 1933 a postage stamp commemorating the 15th Anniversary of the October Revolution (1917-1932). This grey coloured stamp with a face value of 30 kopeks featured a radio transmitter mast and globe to propagate the modernisation of the state to all Soviet people. The designer/ engraver was Ilya Alekseyevich Sokolov (1890-1968). The stamp was printed using a Collotype technique. It was gummed and had watermarks with meanders and flowers. It had a print run of 200,000.
This stamp was part of a larger 1933 collection called "Peoples of the USSR". This series was issued by Goznak to publicise the all-Union labour mobilisation and to articulate the vision of the peoples allocated roles in the Soviet economy. This and other Soviet stamps in this series depicted different ethnic groups such as Kazakhs, Uzbeks, Turkmens, Tajiks, Belarusians, Russians, and Jews. The individuals shown on this specific stamp represented some of these typical nationalities participating in the building of socialism.
That said, another source in my research claimed this Soviet stamp was the first to feature a portrait of a Chinese person (lower right corner). The Chinese man on the stamp was a staff member of a newspaper in Harbin, fluent in Russian. His duties included listening to Soviet radio programmes, then writing news articles for the newspaper. This stamp was issued in 1932 as part of a series commemorating the 15th anniversary of radio in the USSR.
