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).

 Medium flat vellum stock poster (OP-1 in the Eric King guide) is in very good (B/B+) condition; there are tack/staple holes in all four corners, in the left margin and in in top/bottom center margins, along with a thin 1" diagonal corner bend in the lower right corner, a couple of tiny edge nips scattered around the outer margin area, a couple of  light handling dings here and there and a couple of VERY soft bends in the lower right margin, otherwise fine.

 An overall very decent-looking example of this early Bonnie MacLean Fillmore poster.
