Original 1st printing 11&3/8 x 21&7/8" concert poster for the Southbound Freeway and the Bossmen on 11/4/1966 and the MC5 with Southbound Freeway (again) on 11/5/1966, both shows at the Grande Ballroom in Detroit, MI. Art by Gary Grimshaw, image ("Mod Man") is the 5th image in the Russ Gibb Presents/Grande series. Medium-thick flat/vellum stock poster is in good to very good (B to B/B+); one or two pin/tack holes, a flattened center crease, a couple of soft horizontal roll bends, a slight amount of creasing in the lower left corner, a light amount of handling wear/light rippling and a couple of slight splotches of orange ink in the outer margins, otherwise fine. One of Grimshaw's earliest Grande images, complete with the original "Uncle Russ Travel Agency" logo- a VERY cool/early Grande poster.
