This striking blue stamp was issued by the Russian Soviet Federative Socialist Republic (RSFSR) in 1923, during the early Soviet era. It features the portrait of a rugged peasant, symbolizing the working class central to the Soviet state’s ideology. The denomination of 5 rubles reflects the high inflation period of the 1920s. The design is framed with traditional ornamental patterns, adding a folk-inspired touch. Early Soviet issues like this are highly prized among collectors for their historical context and bold representation of proletarian themes.
