Original 1st printing 13&3/4 x 21" concert poster for 1960's UK folk-rock combo the Incredible String Band appearing at the Fillmore West in San Francisco, CA on 9/10/1969.
 
 Designer unknown, image is an un-numbered single-show/one-off image from the Bill Graham/Fillmore series, falling in between the BG 190 and 191 shows.
 
 Medium-thick flat vellum stock poster is in near mint (A- to A-/B+) condition; aside from a couple of minuscule hairline bends and soft handling dings scattered around the outer margin area and a VERY subtle moisture ripple to the paper, this example is just about as sharp/clean as they come.
 
 REALLY nice-looking example of this non-numbered mid-week Bill Graham/Fillmore poster.
