Original 1st printing 21&1/2 x 33&1/2" concert/event poster for the Ann Arbor Blues & Jazz Festival, held at Otis Spann Memorial Field in Ann Arbor, MI from 9/7-9/1973.

 Design by Gary Grimshaw (photo by Tom Copi), the lineup included: Freddie King, Leon Thomas, Count Basie & His Orchestra, J.B. Hutto & the Hawks, Roosevelt Sykes and the Revolutionary Ensemble (9/7), Music of Detroit with CJQ, John Lee Hooker, Yusef Lateef, Charles Mingus, Jimmy Reed, Big Walter Horton, Ray Charles and the Raelettes and more (9/8) and the Johnny Otis Show, Ornette Coleman, Victoria Spivey, Infinite Sound, Joe Willie Wilkins and the King Biscuit Boys, Houston Stackhouse, Luther Allison, Sun Ra, Otis Rush, Homesick James, Lucille Spann, Mighty Joe Young with Carey Bell and Eddie Taylor and Hound Dog Taylor and the Houserockers (9/9).

 Medium glossy-coated index stock poster is in FANTASTIC near mint to excellent (A-/B+ to B+) condition; aside from a couple of tiny creases/dings scattered around the outer margin area (mostly along the left edge), a few stray fingerprints and a slightly rounded top left corner tip, it is a nearly-unbeatable example of the '73 Ann Arbor Blues & Jazz poster.
