Issued by the United Nations Postal Administration – Geneva Office, this striking commemorative stamp promotes global awareness of nuclear disarmament and non-proliferation. The design features a nuclear explosion cloud boldly crossed out in red, symbolizing opposition to nuclear weapons and support for peaceful international cooperation. Inscribed in French “non-prolifération des armes nucléaires,” it reflects Geneva’s diplomatic role in arms-control negotiations. The stamp represents Cold War–era global peace initiatives and UN advocacy efforts. A meaningful thematic addition for collectors specializing in peace, diplomacy, or United Nations issues.
