This stamp from the Kingdom of Cambodia highlights the development of Sihanoukville (Kompong Som), Cambodia’s principal deep-sea port established during the modernization era under Prince Norodom Sihanouk. The design combines a portrait of the national leader with maritime imagery and a port map, symbolizing economic growth and international trade expansion. Issued during the pre-Khmer Republic period, it reflects Cambodia’s post-independence infrastructure ambitions. A desirable thematic piece for collectors of transport, maritime, and Southeast Asian development issues.
