Original 1st printing 14 x 21&3/4" concert poster for the Chambers Brothers with the MC5 and Thyme at the Grande Ballroom in Detroit, MI on 9/1-2/1967. Art by Gary Grimshaw, image is number 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 to very good (B to B/B+); a couple of soft horizontal roll bends (with a bit of minor creasing just to the right of "Chambers"), a couple of fairly-well camouflaged high water marks/moisture stains in the right margin, a slight wave to the paper and a trace amount of handling wear, otherwise fine. An overall fine-looking example of an original 1st printing '67 Grimshaw Grande poster with a great design.
