Original 1st printing 16&3/4 x 29" concert poster for the Grateful Dead and the New Riders of the Purple Sage appearing together at the Taft Auditorium in Cincinnati, OH, on 10/30/1971. 

Art by Alton Kelley and Stanley Mouse, medium glossy stock poster is in very good to excellent (B/B+ to B+) condition; there is a fair amount of curling to the paper (poster was stored rolled up for many years), along with a series of tiny dark pin-prick splatter marks in the right side of the blank area in the lower right edge of the image area, a few stray pinch digs/light creases along the top/bottom margins, a tiny well-camouflaged stress bend or two hiding within the image area and a nearly-invisible diagonal mark in the upper right margin, otherwise fine. Check out a great FM broadcast recording of the gig (complete with Jerry telling off a particularly vocal member of the audience) HERE:
