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 very good to excellent (B/B+ to B+) condition; this example (as with many existing examples) has hand-written (in blue flair pen) date corrections below "Grateful" ("July 14th AND 16th!"), along with a 3" crescent-shaped pressure crease (and a tiny nip tear) in the right center margin, a few VERY soft surface stains along the upper left and right margins (and on the reverse side), a stray handling/stress bend or two hiding within the image area and a hint of surface wear (light scratches and a few minor inking anomalies), otherwise this stands as one of the nicer-looking examples I have come across (many are faded and/or have numerous conditional issues).

 BEAUTIFUL original 1970 Grateful Dead image from a legendary set of Northern California shows, check out the 7/16 show (with Janis Joplin sitting in on "Lovelight") HERE;
