Original 1st printing 12&5/8 x 18&1/2" concert poster for Quicksilver Messenger Service appearing with the Grass Roots and the Family Tree at the Fillmore Auditorium in San Francisco, CA from 4/22-23/1966.

 Art by Bonnie MacLean, image has been designated # "0" in the Bill Graham/Fillmore series (not officially a numbered piece, this one falls between BG 3 and BG 4, it is currently designated OP-1 in the Eric King guide)

 Medium flat vellum stock poster is in excellent (B+) condition; aside from a small semi-pronounced pressure crease/tiny nip tear in the bottom center margin, a 1&1/2" soft diagonal bend in the lower lefrt corner/margin, a couple of tiny corner-tip bumps and a bit of pencil scratch on the reverse side, it is an absolutely GORGEOUS example of this early Bonnie MacLean Fillmore poster.
