This 1 kopek stamp from the Soviet Union was issued in 1929 as part of the definitive series portraying the "Worker, Soldier, and Peasant" designs. Printed in orange, it depicts the face of an industrial worker wearing a cap, symbolizing the proletariat’s role in building the socialist state. These stamps were widely circulated during the early Five-Year Plans and reflect the USSR’s emphasis on labor, industry, and collectivism. A classic piece of early Soviet philately, it remains highly collectible for both historical and thematic collections.
