Original 1st printing 14&1/8 x 20" concert poster for Texas psychedelic legends the 13th Floor Elevators appearing with Moby Grape at the Avalon Ballroom in San Francisco, CA from 11/11-12/1966.
 
 Art by Steve Renick, image is # 34 in the Family Dog/Avalon series.
 
 Medium flat vellum stock poster is in good to very good (B to B/B+) condition; the upper left and lower left/right corners all have tiny bits of pin-prick residue (old tape marks), along with a bit of VERY mild edge wear along the right margin, a few stray soft handling creases hiding within the image area and a series of clear tape remnants/stains/light pulls on the reverse side, otherwise fine.

Very presentable example of this always-popular late-'66 Avalon poster featuring the legendary 13th Floor Elevators.
