This collector-grade Indonesian definitive stamp features a finely rendered merchant vessel cutting through open waters, a classic theme from Indonesia’s early post-independence postal issues. Printed in a rich blue tone, the design highlights the nation’s maritime identity and reliance on sea trade routes across its vast archipelago. The Republik Indonesia inscription anchors the piece in the country’s formative philatelic era. A desirable addition for collectors of ship-themed stamps, Asian definitives, or mid-20th-century postal history.
