Original 1st printing 14 x 20&1/8" concert poster for Jefferson Airplane with the Grateful Dead at the Fillmore Auditorium in San Francisco, CA on 7/15-16/1966. Art by Wes Wilson, image is #17 in the Bill Graham/Fillmore series. Medium-thin flat vellum stock poster is in decent/used (B/B- to B-) condition; multiple pin/staple holes in all of the corners and a few scattered around the outer edges, a couple of light tape stains in the lower left corner and bottom margin (in the ticket outlet area below "Records"), browned tape stains on the reverse, a few surface scratches and tiny splatter stains, corner creasing and the original owner's name hand-written in blue ballpoint in the lower left corner, otherwise a very charming-looking example of this hard-to-find early Fillmore poster.
