This Indonesian definitive stamp, issued in 1966, features a profile portrait of President Sukarno, the founding father and first President of the Republic of Indonesia. The design, printed in a rich brown tone, presents Sukarno wearing his iconic peci (national cap) and formal white attire—symbols of Indonesian identity and leadership.

Issued during a politically transformative period following the end of Sukarno’s rule, this stamp belongs to one of the final series depicting him before the New Order era began under Suharto. The denomination of 25 sen served for basic domestic postage.
