Official promoter-issued 3rd printing 13&5/8 x 20&7/8" concert poster for the 13th Floor Elevators* appearing with the Great Society (featuring Grace Slick, Friday Only) and Sopwith Camel (Saturday only) at the Fillmore Auditorium in San Francisco, CA from 8/26-27/1966. (*Elevators allegedly canceled, replaced by Country Joe & the Fish (Saturday) and Quicksilver Messenger Service (Friday)- this is still debated by various sources)
 
 Art by Wes Wilson (Grace Slick photo by Herb Greene), image is # 25 in the Bill Graham/Fillmore series. (BG-25-RP-3 in the Eric King guide)
 
 Medium flat vellum stock poster is in decent/used (B/B- to B-) condition; there are staple holes (a few with tiny drag tears) in all four corners, along with a couple of rounded/soft corner tips, a 1" tear in the lower right margin, a small drip stain in the upper left margin, a tiny nip out of the lower left margin, a couple of small surface pulls in the bottom right margin that have been colored-in with red marker (home restoration) and a few light handling creases hiding within the image area, otherwise OK... sounds much worse than it looks.

 If you're looking for a used-but-presentable example of this iconic early Fillmore poster, here's your candidate.
