Original 1st printing 22&1/2 x 16&5/8" concert poster for the Grateful Dead appearing with New Riders of the Purple Sage at the Sacramento (CA) Memorial Auditorium on 12/22/1970.

 Art by (and SIGNED in black pen by) Roger Shepherd, image is featured in the Art of Rock book on page 366 (plate 4.101)

 Medium flat index stock poster is in decent/used (B/B- to B-) condition; there are several large "mouse bite" nips out of the lower left margin (about 2"), along with a series of tiny edge nips tears/pressure creases/dings and a bit of light to moderate creasing all around the outer margin area, a few stray surface spots/scuffs here and there, a 10" diagonal bend along the upper left quadrant of the image area, a few stray stress bends here and there... definitely a well-traveled example, but still presentable and it's SIGNED by the artist himself.
