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). *This was keyboardist/vocalist Ron "Pigpen" McKernan's FINAL performance with the Dead.
Medium-thick flat vellum stock poster is in absolutely GORGEOUS near mint (A-) condition; just a trace of handling and a stray edge ding or two, otherwise it is a nearly-unbeatable example of this historic Grateful Dead poster.
Check out a very decent-sounding audience recording of the show HERE;
