Original 1st printing 19&5/8 x 27&3/4" 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 and 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/decent (B to B/B-) condition; a set of tack holes (all four corners and top/bottom center margins), a series of semi-pronounced horizontal bends traversing the image area, numerous tiny thin stress bends scattered throughout the image area, a bit of edge/corner wear, toning and a set of tape pulls on the reverse, otherwise fine.
An overall presentable (if a bit used) 1st printing example of this classic Grateful Dead image from a VERY fondly-remembered run of 1980 shows. Check out a great-sounding soundboard (a Charlie Miller transfer) of the 9/26 show HERE:
