Original 1st printing 8&1/2 x 11" concert flyer for the 13th Floor Elevators (featuring Roky Erickson, who also SIGNED the flyer in black flair pen in the lower right corner) with the Conqueroo at the Doris Miller Auditorium in Austin, TX on 1/7/1967. Art by Mark Weakley, thin flat stock flyer is in fantastic mint/near mint (A/A- to A-) condition; maybe a stray pinch ding or two, otherwise an absolutely gorgeous example of this uncommon early regional Elevators flyer. This was the debut concert from Austin collective "the Electric Grandmother", an early precursor to the Vulcan Gas Company. ULTRA-cool little Elevators item with a neat psychedelic design.
