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 near mint to excellent (A-/B+ to B+) condition; aside from a couple of tiny hairline corner-tip/edge bends, a tiny light surface scuff in the upper left margin and a pair of ULTRA-tiny pulls on the reverse side top margin, it is a STELLAR example of this always in-demand early-'67 Elevators concert 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.
