A rare first printing concert poster for the “avant rock” MC5, Southbound Freeway, and Bossmen at Detroit’s Grande Ballroom in November 1966, with artwork by Gary Grimshaw, who has signed this example at the bottom in pencil.

In beautiful near mint and unused condition, with a soft crease to the bottom left corner and a bit of soft creasing to the left edge near the top—neither of these are significant detractions and this will frame beautifully. 11 1/2” x 22”.   This is number RGP-1966.11.04 in the Grande Ballroom/Russ Gibb poster series.  The only example we’ve had.
