Fiftieth Anniversary of the International Labour Organization

Designed and line-engraved by Jacques Derrey, this regular postage issue features a detailed architectural drawing of the historic International Labour Office building in Geneva, Switzerland, showing its distinct multi-courtyard layout and classicist administrative facades. The lower right corner includes a stylized symbolic emblem depicting two hands working together with a wrench, framing the anniversary timeline of 1919–1969. Historically, this release commemorates the golden jubilee of the International Labour Organization (Organisation Internationale du Travail), a specialized agency of the United Nations dedicated to advancing social justice, regulating working hours, and codifying global labor standards. By issuing this tribute across the Comoro Islands postal network, the French territorial administration underscored the overseas territory's formal alignment with international treaties governing trade union rights and maritime labor codes.
