Original 1st printing 22&1/2 x 35" concert poster for Texas-based psychedelic freak-punks the Butthole Surfers appearing with the Stone Temple Pilots, firehose and Basehead at the Castaic Lake (CA) Amphitheater on 7/821993.

 Art by (and SIGNED and numbered 176/400 in pencil by) COOP (Chris Cooper), medium-thick oak tag stock hand-pulled silkscreen poster (printed with extra-bright day-glo ink) is in very good to excellent (B/B+ to B+) condition; this example exhibits a light to moderate amount of toning, a couple of ultra-tiny edge dings and a slight inking imperfection in the gray pass of ink in the right center margin, otherwise fine.

 Wild-looking COOP image from this early-'90's alt-rock show in Southern California.
