Original 1st printing 21&7/8 x 27&5/8" concert poster for Canned Heat appearing with the Conqueroo and Shiva's Headband at the Vulcan Gas Company in Austin, TX on 5/11/1968. 

 Art by Gilbert Shelton, image ("Canned Heat") is # 21 the VG/Vulcan Gas Company series.

 Medium-thick flat vellum stock poster is in very good to excellent (B/B+ to B+) condition; there is a thin 6" diagonal bend along the upper right margin/corner, along with tiny bends/pressure creases in all four corner tips, a few stray edge dings and tiny creases scattered around the outer margin area, a small 1/2" nip tear in the lower right margin and a series of light splatter stains on the reverse side, otherwise it is a VERY nice-looking example of this HIGHLY psychedelic mid-1968 Vulcan poster from the pen of the one and only Gilbert Shelton.
