The Jefferson Airplane and The Jaywalkers are featured in this early May, 1966 dance concert. Wes Wilson's signature wavy letters come close to filling the paper, and the human head shape is discernable, this time with a gaping maw.
The pre-concert 1st printing measures 14" x 20 1/16" and is printed on vellum with union logo 72 in the lower right corner.
The post-concert 2nd printing was printed in 1967 on uncoated index and omits the union logo. This reprint measures 13 11/16" x 20".
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.
