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 (and SIGNED in black pen by) Lee Conklin, image is # 156 in the Bill Graham/Fillmore series.
Medium glossy stock poster is in VERY sharp/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 the most part this example can not be topped.
One of Lee's weirder Fillmore images, this one has really vibrant/bright colors and a great blues/rock lineup.
