Original 1st printing 8&1/2 x 11" concert flyer for (the) Paul Butterfield (Blues Band) appearing with Johnny Winter and the Flock at Aaron Russo's Kinetic Playground (formerly the Electric Theatre) in Chicago, IL from 8/15-16/1969. 

 Art by (and SIGNED in pencil by) Mark Twain Behrens, thin flat stock flyer is in very good to excellent (B/B+ to B+) condition; there is a small soft 2" moisture stain in the left center margin, along with a light amount of creasing along the upper margin area, a couple of soft surface smudges in the upper right corner/margin and a stray pinch ding or two hiding within the image area, otherwise fine.

 VERY nice-looking example of this oddball mid-'69 concert artifact from the legendary Chicago roller-rink-turned psychedelic ballroom.
