Original 1st printing 13&7/8 x 20" concert/event poster for the Grateful Dead and the Wildflower appearing in a benefit (a fundraiser for the Straight Theatre in Haight-Ashbury), held at the Avalon Ballroom in San Francisco, CA on 5/19/1966. The event also featured performances by beat poet Michael McClure with Ed Bullins and Black Arts West and the Outfit.
Art by Jacob, image is featured in the Art of Rock book on page 106 (plate 2.16).
Medium-thick flat vellum stock poster is in very good (B/B+) condition; a hint of toning, staple holes in the upper left/right corners and top/bottom center margins, a couple of tiny edge nicks, a couple of small pulls and a thin tape residue stain on the reverse, light handling wear and a thin stress bend or two hiding within the image area, otherwise fine.
Very early and somewhat hard-to-find 1st printing 1966 Grateful Dead/Avalon poster from the AOR.
