Original 1st printing 16&3/4 x 22&1/8" concert poster for jazz-rock legends Chicago appearing at Bowen Field House on the campus of Eastern Michigan University in Ypsilati, MI on 10/6/1972.
Art by Gary Grimshaw (Rainbow Graphics), medium flat vellum stock poster is in very good to excellent (B/B+ to B+) condition; there are a series of thin pin-prick white splatter stains dotting the image area, a small rub mark on the "B" of "Bowen", a touch of handling wear, a few ultra-soft horizontal roll bends and a couple of light tape pulls on the reverse, otherwise fine.
An overall superb-looking example of this VERY uncommon early-'70's Grimshaw poster from a small Midwestern college show.
