BG023 is the first example of a rock poster to feature band photographs, these by Herb Greene. Wilson's lettering, by now evolved into a more elegant 'blocky' style, reflected his discovery of the work of Vienna Secessionist designer, Alfred Roller. Together again, Jefferson Airplane, with original vocalist Signe Anderson, and the Grateful Dead shared this August billing.
The handbill was printed once before the concert in blue ink on thin pinkish/coral paper. It measures 5 3/4" x 8 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.
