Original 1st printing 14 x 21" concert poster for Fleetwood Mac (featuring Peter Green) appearing with Creedence Clearwater Revival and blues guitar master Albert Collins at the Fillmore West in San Francisco, CA from 1/16-19/1969.
Art by Lee Conklin, image is # 156 in the Bill Graham/Fillmore series.
Medium glossy stock poster is in ULTRA-CRISP mint/near mint to near mint (A/A- to A-) condition; perhaps there's a stray fingerprint/surface scratch or two hiding somewhere, but for all intensive purposes, this example is unbeatable.
One of Lee's weirder Fillmore images, this one has really vibrant/bright colors and a very cool lineup. Check out an interview with Bill Graham and footage from this show HERE;
