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

 Art by Bonnie MacLean, image is # 0 in the Bill Graham/Fillmore series (BG-0-OP-1 in the Eric King Guide).

 Medium-thick flat vellum stock poster is in excellent (B+) condition; just a soft pinch ding or two hiding within the image area, a thin diagonal hairline bend in the lower left corner tip and a set of tape pulls/stains on the reverse, otherwise it is a SUPERB specimen of this VERY early poster in the BG/Fillmore series.
