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 Quicksilver Messenger Service at the Avalon Ballroom in San Francisco, CA from 9/30-10/1/1966.
Art by Stanley Mouse & Alton Kelley (photo by Ralph Morse), image ("Zebra Man") is # 28 in the Family Dog/Avalon series.
Medium-thick flat vellum stock poster is in VERY sharp near mint (A-) condition; aside from a nearly-invisible pair of pin holes in the top left/right corners, a stray edge/corner ding or two and a whisper of handling (a pinch ding or two may be hiding within the image area), it is an INCREDIBLY sharp 1st printing example of one of the most popular Avalon images in the series.
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:
