A doe-eyed Grace Slick gazes from this poster in one of her last pre-Jefferson Airplane, pre-Grace Slick, Superstar days. 13th Floor Elevator, an up and coming acid rock band in 1965, succumbed to drug problems by 1968 and disappeared from the scene. Wilson's lettering style has now become signature and was recognizable in other, contemporary print advertising.
The postcard was printed in 1967 and matches the 2nd printing of the poster. It measures 4 15/16" x 8 7/16".
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.
