Original 1st printing 6&3/4 x 9&1/2" concert handbill 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 (and SIGNED in black ink by by) Bonnie MacLean image is # "0" in the Bill Graham/Fillmore series (not "officially" a numbered piece).
Thin flat stock handbill is in spectacular near mint (A- to A-/B+) condition; only the slightest trace of handling and a slight discoloration in the top right corner tip, otherwise it is essentially as crisp/clean as you can hope to find.
VERY early Fillmore item in great shape with a really nice bold Bonnie signature.
