This 30-sen definitive stamp from Indonesia, issued in 1966, features a dignified left-profile portrait of President Sukarno, the nation's first head of state and a leading figure in Indonesia’s independence movement. Printed in blue and violet tones, the design captures Sukarno wearing his iconic peci cap — a national symbol of leadership and pride. Part of a widely circulated series, these stamps reflected the political transition of the mid-1960s, marking the closing years of Sukarno’s presidency before the rise of Suharto’s era.
