Original 1st printing 15 x 22" concert poster for Herbie Hancock (with Headhunters) appearing with Freddie Hubbard at Hill Auditorium on the campus of the University of Michigan in Ann Arbor, MI on 2/24/1973.
 
 Art by (and SIGNED in pencil by) Gary Grimshaw (for Rainbow Graphics), medium flat vellum stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a tiny pin-prick indentation/light splatter stain along the upper right margin, a couple of minuscule nips along the upper right margin, a well-camouflaged handling ding or two hiding within the image area and a tiny diagonal bend in the upper right corner tip, it is a GORGEOUS example of this semi-uncommon early-'70's Gary Grimshaw poster from Ann Arbor with a nice large artist's signature.
