Original 1st printing 8&1/2 x 11" concert flyer for Texas psych-rock legends the Conqueroo appearing on 6/27/1968, Bubble Puppy appearing with Afro Caravan on 6/28/1968 and Ezmerelda'z Muzick Amuzementz, again with Afro Caravan on 6/29/1968, all shows held at the Vulcan Gas Company in Austin, TX.
Art by underground comix legend Gilbert Shelton, image ("Flash Comix") is an un-numbered image in the VGC/Vulcan Gas Company series (VGC 1968-06-27/28), this is the YELLOW stock version.
Thin flat stock flyer is in decent (B/B-) condition; there is a 1" diagonal wedge tear in the lower left margin, along with a set of pin/tack holes and a couple of tiny pin-prick stains in each of the four corners, a couple of minor handling dings and a VERY light tape shadow along the bottom edge on the reverse side, otherwise fine.
Conditional issues aside, this is one of the harder-to-find Vulcan Gas flyers from this period. GREAT Gilbert Shelton underground comix design on this one!
