Original 1st printing 14 x 21" concert poster for Spirit appearing with Poco and Gypsy at the Fillmore West in San Francisco, CA from 5/14-17/1970.
Art by (and SIGNED in silver ink by) David Singer, image is # 233 in the Fillmore series.
Medium glossy-coated index stock poster is in near mint to excellent (A-/B+ to B+) condition; a tiny thin 1&1/2" diagonal bend in the lower right corner tip, a VERY soft 3" diagonal bend in the bottom center margin and a hint of surface wear (a few stray surface scratches/fingerprints, a fairly common trait among many later BG posters), otherwise fine.
An overall GORGEOUS ARTIST-SIGNED example of this late-period Fillmore poster.
