Original 1st printing 11 x 17" concert poster for the New Riders of the Purple Sage (featuring Jerry Garcia, Mickey hart and Marmaduke (John Dawson)) appearing at the Matrix in San Francisco, CA on 7/7/1970.

 Art by Mark Twain Behrens, image is featured in the Art of Rock on page 162 (plate 2.105).

 Medium flat vellum stock poster is in near mint to excellent (A- to A-/B+) condition; other than a couple of tiny corner-tip creases and a soft handling ding or two lurking within the image area, it is a BEAUTIFUL example of this early NRPS (with Jerry and Mickey!) poster from the Matrix.
