Original 1st printing 13&3/4 x 20&7/8" concert poster for 1960's UK folk-rock duo the Incredible String Band 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. Medium-thick flat vellum stock poster is in superb near mint (A-) condition; just a trace of wear/light creasing in the top corner tips, otherwise as sharp an example as you can ask for. GORGEOUS-looking (and somewhat hard-to-find) Incredible String Band Fillmore poster from the Fillmore West.
