This striking 100 + 25 sen stamp from the Republic of Indonesia was issued in 1965 to promote CONEFO (Conference of the New Emerging Forces), an international organization proposed by President Sukarno as an alternative to the United Nations, representing developing and anti-imperialist nations.
The design features a bold profile portrait of President Sukarno, rendered in black against a clean white background with red border and text. The surcharge (+25 sen) supported the conference’s initiatives.
An important historical issue, it reflects Indonesia’s strong political stance during the mid-1960s and its aspiration to lead the global “Third World” movement.
