Original 1st printing 19&5/8 x 27&5/8" concert poster for the Grateful Dead's legendary Bill Graham-produced acoustic/electric shows at the Warfield Theatre in San Francisco from 9/25-10/14/1980.

 Art by Dennis Larkins (with Peter Barsotti), image is featured in the Art of Rock book on page 345 (plate 4.45).

 Thick glossy-coated index stock poster is in good (B) condition; the top margin has been hand-trimmed by approximately 1/8" (presumably to fit into a frame) and there are a couple of tiny razor-thin surface scratches in the upper left corner and scattered around the outer margin area (through the "re" of "Theatre" and a few other places), along with a few tiny handling/stress bends here and there and a couple of VERY light tape shadows on the reverse, otherwise fine.

 With the exception of the minor edge trimming and a few minor cosmetic flaws, this example actually looks pretty nice. Check out a great-sounding soundboard (a Charlie Miller transfer) of the 9/26 show HERE:
