This Soviet Union commemorative stamp, issued in 1958, marks the 40th anniversary of the Union of Red Cross and Red Crescent Societies (1918–1958). The design features the Red Cross and Crescent symbols radiating rays of aid and solidarity, along with imagery of humanitarian service, including a soldier, a nurse with children, and the headquarters building flying the Red Cross flag. With its bold red and sepia tones, it embodies the USSR’s commitment to international humanitarian efforts during the Cold War era. A significant thematic issue for collectors interested in medical history, humanitarian organizations, and Soviet philately.
