Issued by the United Nations Postal Administration in 1957, this 3-cent stamp honors the establishment of the United Nations Emergency Force (UNEF)—the first UN peacekeeping mission created in response to the Suez Crisis. The design features the UN emblem surrounded by the inscription “UN EMERGENCY FORCE,” symbolizing global unity and collective security. Printed in deep blue tones, the stamp reflects the UN’s mission to maintain peace and stability during international conflicts. A landmark issue representing the early era of UN peacekeeping efforts.
