Original 1st printing 21 x 28" concert poster for Cold Blood appearing with the Elvin Bishop Group, Boz Scaggs and the Voices of East Harlem at the Fillmore West and the Grateful Dead and the New Riders of the Purple Sage (& assorted friends) appearing with Stoneground at Winterland, both shows held on 12/31/1970 in San Francisco, CA. Art by David Singer, image is # 263 in the Bill Graham/Fillmore series. Medium glossy-coated index stock poster is in very good to excellent (B/B+ to B+) condition; a minor amount of surface wear/handling, a few tiny creases/dings/ink scuffs around the edges and in the corners and a slight bit of softness/minor fraying around the edges in the upper left corner, otherwise a very nice-looking example of this classic double-sized David Singer Fillmore poster featuring none other than the mighty Grateful Dead.
