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+) there are multiple tiny staple holes in all four corners and scattered around the outer margins, along with a couple of tiny smudges in the ticket outlet area, a few nearly-invisible soft handling dings and a thin stress bend or two hiding within the image/outer margin area, a touch of mild toning and a few light scuffs on the reverse, otherwise fine.... the image area is VERY nice.

 GREAT-looking 1st printing example of this popular late-'66 Avalon poster!
