Egypt meets 1920's Deco in the entwining figures of BG039, superimposed on an oddly beach-blanket-striped background. The mood of this poster is less mysterious than many of Wilson's designs.
The postcard was printed after the concert with the 2nd printing of the poster. The utilized "color wheel technique" caused variations throughout the run. The postcard was printed on two different papers; one is smooth 9.5 point plated stock, the other 8.5 point coarse paper with a horizontal rows pattern. It measures 5" x 7 7/8".
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.
