East Totem West was one of the most significant poster companies from the late 60's. Based in San Francisco, their posters are sublime slices of psychedelia and very rare now. consider also purchasing the highly recommended book "The White Rabbit And Other Tales" by Alan Bisbort, which all of ETW's posters are featured in.
