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 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 flat index stock poster is in good (B); there a couple of semi-pronounced horizontal stress/roll creases running along the right half of the image area (the most pronounced bend extends from the "ers" of "Chambers" out to the upper right margin, about 3-4" long), along with a couple of fairly-well camouflaged moisture stains in the right margin (and on the reverse), a moderate of moisture creasing/warping to the paper and a few tiny corner-tip creases, otherwise fine.

 While not at the top of the conditional scale, this example should satisfy most casual collectors, it looks pretty nice overall.
