Duality and motion grip this Wilson poster: male and female, yin and yang, sun and moon, East and West. His colors, silver and a chartreuse-tinted silver, symbolize the rational and spiritual, respectively, and re-circulate in continuous loops.
The poster was only printed once before the concert and displays a great deal of ink variation, especially apparent in the yellow and silver. Paper stock on these can seem slightly different because the paper stock was flipped during the print run. This means that some show fine horizontal rows on the reverse, while others have the horizontal rows on the front, but are barely noticeable under the blank ink on the front of the poster. It measures 14" x 21 1/2".
When the Avalon Ballroom and Bill Graham's Fillmore Auditorium began to hold weekly dance concerts, Wilson was called upon to design the posters. He created psychedelic posters from February 1966 to May 1967, when disputes over money severed his connection with Graham. Wilson pioneered the psychedelic rock poster. Intended for a particular audience, "one that was tuned in to the psychedelic experience," his art, and especially the exaggerated freehand lettering, emerged from Wilson's own involvement with that experience and the psychedelic art of light shows.
