Original 1st printing 18 x 25" concert poster for ZZ Top appearing with Commander Cody And His Lost Planet Airmen at the "Grand Rock & Roll Opening" of Mcnichols Arena in Denver, CO on 8/27/1975. 

 Designer unknown/not credited (show was produced by Barry Fey/Feyline Productions), medium-thick flat index stock poster is in very good to excellent (B/B+ to B+) condition; a set of staple holes (all four corners and bottom center margin), a couple of tiny diagonal bends in the bottom left/right corners with a couple of ultra-tiny "wedge pulls" and a 1/4"tear in the bottom center margin, a touch of edge wear, a whisper of surface wear (a few thin horizontal roll bends) and a touch of curl to the paper from being rolled, otherwise fine. 

 Really nice-looking mid-'70's ZZ Top concert poster from the first-ever rock show held at the then-brand-new arena (it was demolished in 2000).
