Psychedelia was in full flower in this Wilson poster. Only the finely drawn female face featuring delicate sensory pathways is firm, and the words curl around about it like smoke from a pipe. The music of headliner Otis Rush, the Grateful Dead and Canned Heat offered something for everyone.
The postcard was printed once before the concert and measures 4 5/8" x 7 3/4".
There were also some pre-concert double-sized mailers printed that were conjoined with the BG052 image (see BG051/052). They measure 9 5/8" x 7 11/16".
