Original 1st printing 17&7/8 x 24&1/4" hand-pulled silkscreen concert poster for a Hells Angels-sponsored show featuring the Grateful Dead and Bo Diddley appearing together at the Academy of Music in New York City on 3/25/1972.

 Artist unknown (likely a local member of the club), the image is featured in the Art of Rock book on page 404 (plate 4.222).

 Medium-thick flat vellum stock hand-pulled silkscreen poster (printed with florescent/day-glo ink) is in excellent (B+) condition; a few small surface/edge dings and a few very thin horizontal roll-bend creases, but it's otherwise basically fine.... a really impressive-looking 1972 Dead/HA poster and a KILLER display piece.

 A LEGENDARY show in Grateful Dead lore (also Donna Jean Godchaux' first show as an official member), the provenance on this piece is IMPECCABLE... it was saved by a long-time crew member and only recently came out of the frame it had resided in since the '70's; stream the 2nd set of the show (taped by the one and only Jerry Moore) HERE:
