Original 1st printing 13&1/8 x 16&1/8" concert poster for the Grateful Dead appearing with the Flying Burrito Brothers (with Gram Parsons and Chris Hillman) and AUM at the Avalon Ballroom in San Francisco, CA from 4/4-6/1969.

 

 Artist unknown/not credited, image is featured in the Art of Rock on page 111 (plate 2.26).

 

 Medium flat index stock poster is in very good to excellent (B/B+ to B+) condition; aside from a trace of ink smear/streaking from the press, a nearly-invisible set of staple holes (all four corners) and a couple of light handling dings here and there, it is a GREAT-looking example of this totally bizarre Grateful Dead image from the Soundproof series.
