Original 1st printing 13&5/8 x 18" concert poster for the Grateful Dead appearing with the New Riders of the Purple Sage and Rubberduck Company (*along with special guests David Crosby on 7/14 and Janis Joplin on 7/16) at the Euphoria (Pepperland) in San Rafael, CA on 7/14 and 7/16/1970. 

 Art by San Andreas Fault (Tad Hunter), image is featured in the Art of Rock book on page 364 (plate 4.93).

 Medium-thick glossy coated index stock poster is in good (B) condition; this example (as with many existing examples) has hand-written (in green flair pen) date corrections below "Grateful", along with multiple tack/staple holes in all four corners and an the top/bottom center margins, a tiny chunk of paper missing from the top right corner tip, a bit of minor moisture rippling and a couple of light moisture stains along the bottom border, a few stray surface scratches and thin stress/handling creases here and there, a touch of fading/toning and a set of fossilized tape marks on the reverse, otherwise OK... a bit worn, but still all there and the image area looks pretty decent overall.

 AWESOME original 1970 Grateful Dead image from a legendary set of Northern California shows, I haven't had one of these posters pass through my hands in YEARS. Check out the 7/16 show (with Janis Joplin sitting in on "Lovelight") HERE;
