Tapping rich ethnographic information, he demonstrates that these pictographs were not created simply for artistic expression, but were deliberately intended to represent a relatively few number of specific messages. Color photographs depict such things as vision questing, sexuality, the mythic past, life crises, altered states of consciousness, and more. Lacks an index. Oversize: 10.75x12.5<">. Annotation c.
