This is a high-denomination Russian Soviet Federative Socialist Republic (RSFSR) stamp issued in 1921, during the early post-revolutionary years. Printed in carmine red, it depicts the sickle and plow motif, symbolizing agriculture and labor—themes central to the Soviet ideology. The large 1000 rubles face value reflects the severe hyperinflation of the early 1920s, making such high denominations necessary for postal use. Imperforate and printed on thin paper, this issue is an important piece from the Civil War and early Soviet period, highly sought after for both historical and thematic collections.
