Original 1st printing 17 x 19&1/4" concert poster for the Byrds appearing with Al Kooper, Bangor Flying Circus, One Man's Family and the cast of "Second City" at the Aragon Ballroom in Chicago, IL on 5/1/1970.

 Design by underground comix legend Skip Williamson, medium-thick flat vellum stock poster is in very good to excellent (B/B+ to B+) condition; there are a couple of thin edge creases running along the top/left margins, along with a couple of thin diagonal corner bends, a few soft handling dings and tiny pin-prick surface spots scattered around the image area and a VERY thin diagonal bend in the upper right margin (about 5-6"), otherwise fine.

 Very interesting-looking early-1970 concert artifact from the legendary (and still operating) Chicago ballroom.
