By the time of the formation of the Union of Soviet Socialist Republics, with its more than 200 million inhabitants, there was an urgent need for more stamps of various face values that would reflect the change of the state name.

New stamps were also required due to the monetary reform in the Soviet Union and the introduction of the chervonets (equal to 10 roubles), backed by the gold standard.

Representatives of the three main strata of the population, the Worker, the Peasant, and the Red Army Soldier, were depicted on the stamps.

Live models from his hometown of Shadrinsk were chosen for producing at first sculptures of those three types.

In March 1924, the new ruble based on the gold standard was finally introduced, and the stamp prices were fixed.
