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 (A- to A-/B+) condition; aside from a couple of tiny corner-tip bumps and a soft handling ding or two lurking within the image area, it is an absolutely STUNNING example of this early NRPS (with Jerry and Mickey!) poster from the Matrix.
