Original 1st printing 8&1/2 x 14" oversized concert flyer for the Grateful Dead at the Memorial Auditorium in Buffalo, NY on 9/26/1973. Artist unknown, thin flat stock flyer is in superb mint/near mint (A/A-) condition; an awesome-looking example of this semi-obscure early '70's regional Grateful Dead image; check out a fantastic-sounding Charlie Miller transfer of the gig (featuring Martin Fierro and Dave Ellis on horns) HERE:
