Original 1st printing 14 x 20" concert poster (a benefit for the Delano Grape Strikers/NFWA (National Farm Workers Association), which featured El Teatro Campesino (California Theater Troupe), Quicksilver Messenger Service and the San Andreas Fault Finders appearing at the Fillmore Auditorium in San Francisco, CA on 7/10/1966.
Art by Wes Wilson, image is not part of the numbered Bill Graham/Fillmore series (this show falls on the day after the BG 16 show) and appears in the Art of Rock on page 150 (plate 2.69) in the "Fillmore Auditorium Benefits" chapter.
Medium flat vellum stock poser is in excellent (B+) condition; there are tack/pin holes in all four corners, a thin 1'; diagonal bend in the top left corner, a few well-camouflaged soft pinch dings and a trace of surface wear (a tiny scratch/pin-prick spot or two), otherwise it is a VERY sharp/bright example of this early (1966) 1st printing Fillmore benefit poster.
