Original 1st printing 14 x 21" concert poster for the Grateful Dead appearing with the New Riders of the Purple Sage and Southern Comfort at the Fillmore West in San Francisco, CA from 6/4-7/1970.
Art by David Singer, image is # 237 in the Bill Graham/Fillmore series.
Medium glossy coated index stock poster is in near mint to excellent (A-/B+ to B+) condition; there is a trace of surface wear (tiny surface scratches/stress bends/pinch dings and a pair of almost-invisible surface indentations) and a couple of VERY thin bends in the corner tips, otherwise fine.
VERY nice-looking example of this classic 1970 David Singer-designed Grateful Dead poster from the Fillmore.
