Original 1st printing 18 x 25&1/2" concert poster for the Grateful Dead appearing with the Robert Cray Band, Strangers with Candy, Tattoo and the Flying Karamazov Brothers at the Oregon Country Fairgrounds in Veneta, OR on 8/28/1982 ("2nd Decadenal Picnic", sponsored by the Springfield Creamery).

 Designer unknown, image is featured in the Art of Rock on page 376 (plate 4.137). 

 Medium-thin semi-gloss textured stock poster is in excellent (B+) condition; there is a hint of moisture warp/rippling to the paper (primarily concentrated in the upper left corner/quadrant), a couple of light handling dings here and there, a few tiny edge tears in the upper right margin and a hint of surface wear, otherwise fine. 

 Very amusing Dead poster from the 10th Anniversary of the 1972 Veneta "Field Trip" shows, stream the show HERE;
