Original 1st printing 13&3/4 x 22&1/2" concert poster for Chicago blues legend Muddy Waters appearing with Quicksilver Messenger Service at the Fillmore Auditorium in San Francisco, CA from 11/4-6/1966.
Art by Wes Wilson, image is # 35 in the Bill Graham/Fillmore series.
Medium flat vellum stock poster is in excellent to near mint (A-/B+) condition; there is a tiny 1/2" tear in the right center margin (sealed on the reverse with clear tape), a tiny surface scuff in the lower right margin, a few nearly-invisible handling/stress bends hiding within the image area, a set of microscopic pin holes (all four margins/corners) and a whisper of surface wear, otherwise fine.
An absolutely GORGEOUS (and very well-inked) example of the 1st printing BG 35 poster.
