Original 1st printing 11 x 8&1/2" concert flyer for Frank Zappa and the Mothers of Invention appearing with Fleetwood Mac and Rory Gallagher at the Milwaukee (WI) Arena on 10/20/1971. Designer unknown, thin flat stock flyer is in excellent (B+) condition; a trace of handling and a fingerprint smudge just to the right of "20", otherwise a superb-looking example of this obscure early '70's FZ flyer from the Midwest.
