Original 1st printing 14 x 22&1/8" concert/event poster for the Ann Arbor Blues Festival, held at Otis Spann Memorial Field in Ann Arbor, MI from 8/7-9/1970.

 Design by Serigraphics, the lineup included: Bukka White, Howlin' Wolf, John Lee Hooker, Albert King, Luther Allison, Big Mama Thornton, Otis Rush, Mance Lipscomb, Junior Parker, Son House, Joe Turner, T-Bone Walker and MANY more.

 Extra-thick flat stock (printed on a thick piece of Crescent art board) hand-pulled silkscreen poster is in very good to excellent (B/B+ to B+) condition; there is a tiny bit of pressure creasing/wear in all four corner tips, along with a bit of light surface scuffing/dirt and a couple of tiny edge dings/pressure creases scattered around the outer margin area, otherwise it is a GREAT-looking example of the first AABF poster of the 1970's.

Just guessing by the format, I'm guessing there weren't a lot of these printed.
