This 1966 pair from Indonesia features the portrait of President Sukarno, issued as part of the mid-1960s definitive and semi-postal charity series. The blue 30 sen stamp represents the standard definitive issue, while the red 1.25 + 1.25 semi-postal stamp bears the “Conefo” inscription, indicating a surcharge collected for special national programs connected with the Conference of the New Emerging Forces initiative. The clean engraved portrait design reflects Indonesia’s nation-building era and is popular among collectors specializing in Asian political history, presidential issues, and semi-postal charity stamps. A matched pair such as this adds historical depth and thematic interest to modern Indonesia collections.
