Stella. Hagmatana III, 1967.
It's 10 feet tall and it does not want to be anything more than surface. In the 1972 video he talks about 1959, which is the equivalent of 2011 from our own time. The pace of social change after 1960 was incredible. Also I think pot must have been milder, for him to just keep going on like that, never mind the camera person and the b&w/color.
