Original 1st printing 15 x 22" concert poster for an all-blues/R&B show featuring Jr. Walker & the All-Stars, Bobby "Blue" Bland, Luther Allison and the Mojo Boogie Band (featuring Steve MacKay of the Stooges) appearing together at Hill Auditorium on the campus of the University of Michigan in Ann Arbor, MI on 1/20/1973.

 Art by Gary Grimshaw, medium-thin flat vellum stock poster is in good to very good (B to B/B+) condition; there are decent-sized tack/nail holes in all four corners, along with a bit of corner-tip wear (a tiny wedge pull/bend/nips), a 1/2" tear in the upper right margin, a couple of tiny nip tears along the lower margin, light handling wear, a light amount of toning, a tiny stress bend/pin-prick indentation or two hiding within the image area and a set of tape pulls on the reverse, otherwise it is a fine-looking example of this somewhat hard-to-find Grimshaw poster from Hill Auditorium.
