Original 1st printing 11 x 8&1/2" concert/event flyer for the Free Detroit Blues Festival, held at the Belle Isle Bandshell in Detroit, MI on 7/15/1973.

 Design by Gary Grimshaw, the lineup included: Washboard Willie, L.C. Minor, Little Jr. Cannady, Bo Bo Jenkins, Daddy Walton, Dr. Isiah Ross, Eddie Burns, Boogie-Woogie Red, Baby Boy Warren, Detroit Willie and Little Mack Collins.

 Thin flat stock flyer is in decent (B/B-) condition; there are semi-pronounced horizontal/vertical folds, diagonal corner creases, a bit of outer margin wear (a few tiny edge nicks/dings and a nip tear or two), a series of thin scuffs and pin-prick stains in the lower margin, a moderate degree of handling wear/creasing, a touch of toning and a bit of pencil scratch ("1973") just above "1-6pm", otherwise OK.

 VERY obscure early-1970's Gary Grimshaw item from Detroit, this is the first one of these I have ever seen.
