That's Chief I-looka-Kunt-in-this-hat. Well known bad-ass and leader of the Dopey-Kuntz tribe. They were feared for their lack of humour, bucolic stupidity and outrageous dress sense. Chief I-looka was in fact the last chief of the tribe as they were slaughtered to a man by the other Native Americans, for giving them all a bad name. This event happened at the well known battle of Medicine Hat and is celebrated unwittingly by British Squaddies getting totally shit-faced and collapsing in a heap.
