Original 1st printing 14&1/4 x 22" concert poster for the 13th Floor Elevators (featuring Roky Erickson) appearing with the Conqueroo at the City Coliseum in Austin, TX on 2/10/1967.

 Art by Mark Weakley (inspired by Wes Wilson), medium-thick flat index stock poster is in GORGEOUS near mint (A- to A-/B+) condition; just one or two tiny edge dings and a thin line of toning/age spotting running along the bottom/left margins and that's IT. An absolutely FANTASTIC-looking specimen of this VERY early pre-Vulcan poster from Austin.

 This was the third concert produced by the Austin hippie collective "the Electric Grandmother", an early precursor to the Vulcan Gas Company. We also have the flyer for this show listed separately.
