Original 1st printing 8&3/8 x 11" concert flyer for Bubble Puppy appearing with the Zig-Zag String Quartet at the Vulcan Gas Company in Austin, TX on 9/6-7/1968. (also: "Killer Chicken & the Dumplings" on 9/5)
Art by JFKLN (Jim Franklin), image "Cubic Chair" is an un-numbered part of the VGC series (VGC 1968-09-06/07).
Ultra-thin flat stock flyer is in fantastic near mint (A-/B+) condition; only a couple of soft stray handling dings, a whisper of toning and a test pass of ink (red) from another image on the reverse (*most of them are like this), otherwise fine.
VERY, VERY uncommon and hard-to-find Vulcan Gas flyer with a really strange Jim Franklin design.
