Original 1st printing 5&5/8 x 8&1/2" concert handbill for 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 and Alton Kelley, image ("Zebra Man") is # 28 in the Family Dog/Avalon series. (OHB-A in the Eric King guide)
 
 Thin flat stock handbill is in good/decent (B/B-) condition; the right margin appears to have been hand-trimmed (slightly uneven edge) and there are a couple of semi-soft diagonal bends in the lower left/right corners, but aside from that it is a pretty sharp-looking example overall.
