Original 1st printing 11 x 17" concert poster for multi-instrumentalist Shawn Phillips appearing with Daryl Hall & John Oates at the world-famous Armadillo World Headquarters in Austin, TX from 10/20-21/1975.
 
 Art by Guy Juke, medium-thin flat vellum stock poster is in excellent (B+) condition; there is a VERY thin hairline bend along the top border of the image area (just beneath "Shawn", about 5" long), along with a couple of slightly soft corners, a whisper of handling wear and a couple of tiny pin-prick spots in the 3-5:00 area of the interior circle, otherwise fine.  

Very early out-of-state Hall & Oates appearance.
