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; a set of well-camouflaged tack/pin holes (top/bottom center, just to the left/right and directly underneath "El Teatro Campesino"), a soft 1" bend in the top right margin, a couple of stray pinch dings along the bottom margin and a tiny stain on the "c" of "Encore" and a nearly-invisible soft bend in the lower left margin, otherwise it is a GORGEOUS example of this very early (1966) 1st printing Fillmore benefit poster.
