Issued in 1966 by the Republic of Indonesia, this 80 sen definitive stamp features a striking red profile portrait of President Sukarno, the nation’s first head of state and a central figure in Indonesia’s struggle for independence. The minimalist design, with Sukarno wearing his characteristic peci cap, embodies national pride during a turbulent political era. The year of issue, 1966, appears within a pentagon emblem, and the denomination and country name are boldly printed below. This issue remains a significant piece in Indonesia’s post-independence philatelic history.
