Original 1st printing 13&3/4 x 20&7/8" concert poster for 1960's UK folk-rock duo the Incredible String Band appearing at the Fillmore West in San Francisco, CA on 12/10/1969.
 
 Designer unknown, image is an un-numbered single-show/one-off image from the Bill Graham/Fillmore series, falling in between the BG 205 and 206 shows (and just a few days after Altamont).
 
 Medium-thick flat vellum stock poster is in very good to excellent (B/B+ to B+) condition; there are pin holes in all four corners with a tiny drag tear in the top left corner, along with a slight surface smudge beneath "The", a few ultra-soft handling dings here and there and a stray pin-prick spot or two hiding within the image area, otherwise fine.
 
 VERY nice-looking example of this semi-uncommon 1969 non-numbered poster from the Fillmore West.
