Original 1st printing 10&3/8 x 16&7/8" concert poster for Dutch prog-rock band Focus appearing with Joe Walsh & Barnstorm and Blue Oyster Cult at Memorial Hall in Kansas City, KS on 4/11/1973.

 Designer unknown/not credited, medium flat index stock poster is in very good to excellent (B/B+ to B+) condition;  a bit of a vertical curl to the paper, light/subtle toning, a small 1/2" tape mark in the bottom center margin, a couple of nearly-invisible pin hiles in the top margin/corners, a touch of edge/corner wear, series of VERY well-camouflaged stress/handling bends hiding within the image area and a tiny black smudge (could be a tiny print flaw) in the lower right corner, otherwise fine.

 Nifty little early-'70's concert poster from Kansas with an unusual design.
