This striking Soviet Russia (RSFSR) issue from 1923 features a muscular worker breaking free from chains, symbolizing liberation and the triumph of the proletariat. Printed in brown, the design reflects the revolutionary spirit of the early Soviet period. The inscription "РОФСР" identifies the Russian Soviet Federative Socialist Republic, and the large denomination of 4 rubles highlights the inflationary economy of the time. A key piece from the classic early Soviet "Freedom from Chains" series, it holds strong historical significance and is sought after by collectors of Russian revolutionary-era philately.
