Korupun 1, Korupun 2, andKorupun 3 are about the pioneer days (1963-1968) of discovering and opening to missionary work Korupun, Papua (Irian Jaya), Indonesia by the Masters family, and the Kimyal tribe of that area. This is amazing historic stuff. Notice the red dot on the map up there at the top left. That's where Korupun is.
I have also put up a few photos from my own days at Korupun, 1974-1991. You can find them at Korupun 4.
