This rare stamp was issued during the Russian Civil War period, featuring the double-headed imperial eagle, a symbol of Tsarist authority. Printed in blue-green, it carries the inscription “Русская Почта” (Russian Post) and a denomination of 50 kopecks. Produced under emergency conditions, these issues often show crude printing, adding to their historic value.
