Original 1st printing 18&1/2 x 18&3/4" concert poster for Frank Zappa and the Mothers of Invention appearing with Balderdash at the Cincinnati (OH) Music Hall on 10/21/1970. Designer unknown/uncredited, medium-thick flat index stock poster is in used (B-) condition; heavy corner wear (missing paper in 3 of the four corners, staple holes/pulls, etc., moisture/surface wear (numerous scattered moisture stains, including a large 1&1/2" brown burn mark just to the right of the "F" of "Frank"), handling, edge wear, tape marks on the reverse... it's fairly obvious that this one was hung up outside at the time. Still, a very cool little low-run regional Zappa poster from the Ludlow Garage promotional team with a neat design.
