Blues master Muddy Waters couldn't appear more royal than he does here, decked out like a British monarch complete with ruff. San Franciscans turned out in huge numbers to hear this king perform his sets live.
The 1st printing of the poster is on .0075" stock and exhibits almost solid pink lettering as a result of using a heavy dot screen. It was printed before the concert and measures 13 3/4" x 22 1/2".
The 2nd printing is on porous stock with a matte finish. The green color ranges from light to dark as a result of ink inconsistencies, and the pink lettering is significantly lighter than it is on the original. It measures 13 3/4" x 22 1/2" and was printed after the concert.
The 3rd printing is on plated uncoated index that presents a shiny finish. Upon close inspection, a horizontal pattern is evident in the paper, which is .0090" thick. The post-concert 3rd printing measures 13 13/16" x 22 3/8".
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.
