Original 1st printing 16&5/8 x 21&7/8" concert poster for the Grateful Dead appearing with the New Riders of the Purple Sage at Hill Auditorium on the campus of the University of Michigan in Ann Arbor, MI on 12/15/1971.

 Art by Gary Grimshaw, image is featured in the Art of Rock book on page 393 (plate 4.187). *this version does not have the local ticket-outlet imprint

 Medium-thick vellum stock poster is in very good (B/B+) condition; there are decent-sized tack holes in all four corners, along with a small 1/4" tear along the lower left margin, a bit of light handling wear (mostly around the outer edges), a thin 4" diagonal hairline crease and a VERY soft roll bend along the upper left margin, a couple of semi-soft creases along the bottom margin and a nearly-invisible set of tape shadows on the reverse side, otherwise it is a very decent-looking example of this classic Grimshaw Grateful Dead image from the early '70's.
