Original 1st printing 14 x 21" concert poster for Humble Pie (featuring Steve Marriott and Peter Frampton) with Swamp Dogg and Shanti at the Fillmore West in San Francisco, CA on 5/13-16/1971. Art by (and SIGNED in black flair pen by) David Singer, image is # 280 in the Bill Graham/Fillmore series). Medium glossy coated index stock poster is in very good to excellent (B/B+ to B+) condition; a very soft horizontal roll bend in the right center margin, a few scattered surface scuffs and tiny fingerprints here and there, a trace of toning along the bottom edge and a stray handling ding or two, otherwise fine- it looks great in person. Real nice late-period SIGNED David Singer Fillmore poster.
