Original 1st printing 8&1/2 x 11" concert flyer for a benefit for the Ann Arbor Sun, featuring the Boogie Bros., held at the Blind Pig in Ann Arbor, MI on 7/4/1973.

 Art by (and SIGNED in pencil by) Gary Grimshaw, ultra-thin flat stock flyer is in STUNNING near mint (A-) condition; aside from a nearly-invisible soft diagonal bend in the upper left corner and the slightest trace of handling wear, it is an absolutely UNBEATABLE ARTIST-SIGNED example of this INCREDIBLY obscure early-'70's Gary Grimshaw item from Ann Arbor.
