Original 1st printing 22&1/8 x 16&7/8" concert poster for Indian sitar master Ravi Shankar appearing at Hill Auditorium on the campus of the University of Michigan in Ann Arbor, MI on 9/15/1972.
 
 Design by Gary Grimshaw (for Rainbow Graphics), medium flat vellum stock poster is in very good (B/B+) condition; there are a few small tears scattered around the outer margin area (just beneath the right side of the ticket outlet strip and in the upper left, left-center and lower left margins, five total), along with a bit of creasing/wear in the lower right corner, a thin horizontal bend above "Gary Grimshaw"/Rainbow Graphics),  a couple of tiny pressure creases scattered around the outer margin area and a tiny bend in the upper left corner tip, otherwise fine.

 INCREDIBLY COOL graphic design on this one!!!
