Original 1st printing 8&1/2 x 11" concert flyer for the Grass Roots appearing with Big Brother & the Holding Company (pre-Janis) and the Buddha from Muir Beach at the Avalon Ballroom in San Francisco, CA from 6/3-4/1966.
Art by Victor Moscoso, image("A Stone Facade) is # 11 in the Family Dog/Avalon series.
Thin flat stock flyer is in very good (B/B+) condition; there are a few light surface scuffs and handling dings throughout, a number of tiny pin/staple holes (all four corners and running along the top margin), a tiny stress bend or two hiding around the outer order area and a piece of clear tape on the reverse, otherwise fine.
Very decent-looking example of Victor's VERY FIRST rock poster image.
