This 6 Rupiah stamp from the Republic of Indonesia features a formal portrait of President Sukarno, the nation’s founding father and first head of state. Printed in a rich violet shade, the design captures Sukarno in traditional attire, wearing the peci cap—a symbol of national pride and unity. Part of Indonesia’s definitive series from the late 1950s to early 1960s, these stamps reflected the spirit of independence and the young republic’s emergence on the world stage. A significant issue for collectors of post-colonial Asian and political history themes.
