Original 1st printing 16&7/8 x 21&3/4" concert poster for the Grateful Dead appearing with the New Riders of the Purple Sage at the Hollywood Bowl on 6/17/1972.

 Design by Pacific Presentations (photo by Herb Greene), image is featured in the Art of Rock on page 372 (plate 4.122).

 Medium-thick flat vellum stock poster has been professionally restored to excellent (B+) condition; all four corners have had pin/tack hole repair (a single hole remains in the "a" of "Dead"), along with a well-camouflaged flattened diagonal bend/scratch going through "Reserved" in the lower left margin) and a couple of tiny pin-prick rust spots on the reverse side top margin, otherwise it is a GREAT-looking example overall. 

 An always-in-demand mid-1972 Grateful Dead concert poster from Ron "Pigpen" McKernan's FINAL performance with the Dead. Check out a very decent-sounding audience recording of the show HERE:
