This 10 Rupiah definitive stamp from Indonesia features a distinguished portrait of President Sukarno, the nation’s first head of state and a central figure in the independence movement. Printed in a deep blue-grey tone, it belongs to the classic mid-20th-century Sukarno portrait series that defined the country’s early republican postal identity. The stamp showcases Indonesia’s strong post-independence visual style, with clean typography and a traditional wavy-line frame. A staple in Southeast Asian postal history, it remains a desirable piece for collectors focusing on Indonesian leadership issues and early republic material.
