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.
Medium-thick flat vellum stock poster is in GORGEOUS mint/near mint to near mint (A/A- to A-) condition; just a trace of surface wear (a soft fingerprint smudge or two) and that's IT.
ULTRA-crisp example of this oddball mid-week Incredible String Band Fillmore poster from the Fillmore West.
