Issued by Cambodia to commemorate the anniversary of the Fondation du Sangkum, this finely engraved 25 centimes stamp features a youthful portrait of Norodom Sihanouk, the architect of modern Cambodian neutrality and nation-building. The design carries the patriotic slogan “Paix – Indépendance – Neutralité – Prospérité,” reflecting the Sangkum political movement’s ideals. Printed in a rich single-colour intaglio style, the sharp line work and formal bust composition give it strong classic appeal. Bilingual French and Khmer inscriptions add historical depth and colonial-era postal character. A desirable addition for Cambodia, monarchy, or Southeast Asia thematic collections.
