Original 1st printing 12 x 16&1/4" concert poster for Country Joe & the Fish appearing with the Steve Miller Band, Tim Hardin, Buddy Guy and the Sons of Champlin at the C.U. Stadium (Folsom Field) on the campus of the University of Colorado in Boulder, CO on 9/7/1969.

 Art by Hess, medium-thick flat index stock poster is in excellent (B+) condition; there is a tiny 1/4" partial wedge pull/tear in the lower left corner of the image area (just above "Spontinuity"), along with a couple of VERY soft/light surface smudges, a nearly-invisible thin vertical bend in the upper left margin and a few very well-camouflaged pinch/stress bends, otherwise fine.

 KILLER design on this low-run regional poster from a very eclectic (and electric!) multi-act show in the Colorado mountains.
