Original 1st printing 13&7/8 x 22" concert poster for the Chambers Brothers with the Nice (featuring Keith Emerson) and King Crimson (with Greg Lake and Robert Fripp) at the Fillmore West in San Francisco, CA on 12/11-14/1969. Art by (and SIGNED in silver pen by) David Singer, image is # 206 in the Bill Graham/Fillmore series). Medium glossy coated index stock poster is in good to very good (B to B/B+) condition; an ultra-soft horizontal roll bend in the left center margin, an area of light creasing and moisture rippling in the lower right corner, a slight water stain and a touch of fraying in the lower left corner (and another subtle water mark in the upper left margin), a soft diagonal roll bend/crease in the upper right corner and a few scattered surface scratches/fingerprints, otherwise a very presentable example of this late-'69 Singer Fillmore poster with a nice fat signature.
