Original 1st printing 11&3/4 x 24&1/4" concert poster for Jefferson Airplane, the Paul Butterfield Blues Band and the Grateful Dead appearing together at Winterland (*canceled at Winterland/moved to the Fillmore) in San Francisco, CA from 10/7-8/1966 (another show was subsequently added on Sunday the 9th).
Art by Wes Wilson, image is # 30 in the Bill Graham/Fillmore series.
Medium flat vellum stock poster is in very good (B/B+) condition; there is a single tack hole in the top center margin, a pair of semi-pronounced diagonal bends in the 7-9:00 areas of the circle extending into the upper right margin, a hint of toning, a whisper of handling/edge wear, a couple of tape shadows on the reverse and a touch of curl to the paper, otherwise fine.
An overall very decent-looking 1st printing example of this early (1966) Wes Wilson Bill Graham poster with a great op-art design and a KILLER lineup.
