Issued by the Soviet Union in April 1955, this 40 kopeks commemorative stamp honors the International Conference of State Institution, Communication, Municipal Services, and Health Workers. The design features two hands clasped in a handshake, symbolizing international solidarity, set against a backdrop of world maps and conference lettering. It reflects the Soviet emphasis on unity among workers across nations during the Cold War era. A historically rich piece, it appeals to collectors of labor movement themes, Cold War philately, and Soviet commemoratives.
