This 4-kopeck postage stamp, issued by the Soviet Union in 1977, celebrates the efficiency and modernization of the USSR postal service. The design features a smiling postal worker promoting letter collection (“Выемка писем”), a postman emptying a public mailbox, and a postal vehicle before the grand central post office building. The hammer and sickle emblem and the inscription “ПОЧТА СССР” (Post of the USSR) symbolize state communication and reliability.

A collector’s note: this stamp is part of a broader 1970s Soviet series highlighting various aspects of national postal operations—an era marked by growing mechanization and improved delivery systems.
