Original 1st printing 14&1/8 x 19&7/8" concert poster for Texas psychedelic fuzz-rock legends the 13th Floor Elevators (featuring Roky Erickson) appearing with the Sir Douglas Quintet (featuring Doug Sahm and Augie Meyers) at the Avalon Ballroom in San Francisco, CA from 9/2-3/1966.
Art by Stanley Mouse and Alton Kelley, image ("Tree House") is # 24 in the Family Dog/Avalon series.
Medium-thick flat vellum stock poster is in GORGEOUS mint/near mint to near mint (A/A- to A-) condition; aside from a tiny nick in the lower right margin, an almost invisible corner bump or two and one or two soft handling dings here and there, this example is essentially as bright/crisp as they come.
A VERY clean example of this EARLY 1st printing FD poster, this poster (and several others we are featuring in this sale) comes from the collection of underground comix artist (and personal friend of Rick Griffin and Rick Shubb) George Metzger. Read more about George HERE:
