Original 1st printing 17&1/8 x 22&1/8" concert poster for Ten Years After appearing with Procol Harum (with Robin Trower) at Sam Houston Coliseum in Houston, TX on 7/25/1970. 

 Designer unknown/not credited, extra-thin flat index stock poster is in very good (B/B+) condition; there are tack/pin holes and a couple of tiny nip tears in the corner tips, along with a light to moderate amount of handling wear/light creasing throughout, a series of tiny creases scattered around the outer margin area, a few thin stress bends here and there and a couple of VERY thin diagonal corner bends in the upper left/lower right corners, otherwise fine.

 REALLY COOL-LOOKING low-run regional concert poster featuring a pair of top-notch British headliners.
