Original 1st printing 14 x 21&3/4" concert poster for the Chambers Brothers appearing with the MC5 and Thyme at the Grande Ballroom in Detroit, MI on 9/1-2/1967.

 Art by (and SIGNED in pencil by) Gary Grimshaw, image is # 42 in the Russ Gibb Presents/Grande series and is featured in the Art of Rock book on page 299 (plate 3.140). 

 Medium-thick flat index stock poster is in absolutely fantastic  near mint (A-) condition; aside from a pair of almost-invisible pinch bends in the top right/lower right margins, this is a VERY clean/crisp example. KILLER 1st printing '67 Grimshaw-designed Grande Ballroom poster from the AOR.
