Original 1st printing 21 x 28" concert poster for Cold Blood with the Elvin Bishop Group, Boz Scaggs and the Voices of East Harlem at the Fillmore West and the Grateful Dead with the New Riders of the Purple Sage (& assorted friends) and Stoneground at Winterland, both shows held on 12/31/1970 in San Francisco, CA. Art by (and SIGNED in silver ink by) David Singer, image is # 263 in the Bill Graham/Fillmore series. Medium glossy coated index stock poster is in excellent (B+) condition; a couple of tiny corner creases in the top right/bottom left corners. a very minor amount of surface wear, a stray edge ding or two and a trace of handling, otherwise a very sharp-looking example of this classic double-sized David Singer Grateful Dead Fillmore poster with a nice bold silver signature.
