The printing variations of BG034 are based primarily on the stock used, so it may be necessary to compare the different printings side by side.

The pre-concert 1st printing is on coarse .0085" stock that measures 13 5/8" x 19 1/8". Upon close inspection, there are fine vertical lines in the paper pattern. The colors in this original printing are light sensitive, and they fade and lose their vibrancy very quickly.

The 2nd printing is on smooth stock .0075" thick. There are no discernable patterns or lines in this stock. This poster was printed after the concert and measures 13 11/16" x 18 15/16".

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.
