Original 1st printing 8&1/2 x 11" concert/event flyer for "Bedrock One", a benefit for the Communications Company (publishers of the Diggers' Haight-Ashbury neighborhood newsletters), held at California Hall in San Francisco, CA on 3/5/1967.

 Participants/performers included the San Francisco Mime Troupe, the Committee, the Steve Miller (Blues) Band, the Orkustra, Dino Valenti and more.

 Art by Robert Crumb, image (pink stock) is featured in the Art of Rock on page 177 (plate 2.153), this is the GREEN STOCK version.

 Thin flat stock flyer is in excellent (B+) condition; there is a 1" diagonal bend in the upper left corner, along with a few semi-soft handling creases here and there, a bit of minor edge creasing along the right margin and a bit of minor ink spread on the reverse side, otherwise it is an absolutely FANTASTIC example of this VERY hard-to-find version of this always-in-demand R. Crumb item from the AOR (the only commissioned event/concert flyer he did at the time).
