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 from 9/1-2/1967.

 Art by (and SIGNED in black razor-tip pen 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 near mint (A- to A-/B+) condition; aside from a bit of light creasing along the top margin, a soft diagonal bend in the lower right corner and a couple of tiny pin-prick surface spots, it is an EXCEPTIONALLY NICE-LOOKING ARTIST-SIGNED example of this perennially popular Grimshaw Grande poster.
