Original 1st printing 16&1/2 x 21&7/8" concert poster for Canadian folk hero Gordon Lightfoot appearing at Hill Auditorium on the campus of the University of Michigan in Ann Arbor, MI on 2/12/1972. (*also mentions a Delaney & Bonnie and Friends/Billy Preston show at Hill the following weekend (2/19) 

 Art by Gary Grimshaw, medium-thick vellum stock poster is in excellent (B+) condition; just a few scattered soft handling dings, a tiny tape residue mark in the bottom right margin and a series of small adhesive residue remnants/light pulls on the reverse, otherwise fine.

 MEGA-uncommon early '70's Gary Grimshaw poster from Ann Arbor, this one almost never turns up.
