Bill Graham's early productions always offered the audience more than musical entertainment. Lenny Bruce's appearance here was daring, although more pathetic than powerful, and is memorable because it was his last performance before he died.
The postcard was first printed after the concert with the 2nd printing of the poster. It is differentiated by its large margins and is printed on porous rough stock. It measures 5 1/16" x 8".
The 3rd printing is on smooth plated stock and measures 5 1/16" x 7 1/2". It was also printed after the concert.
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.
