Original 1st printing (no script "W"/flat stock) 14 x 21&1/2" concert poster for the Grateful Dead appearing with Quicksilver Messenger Service and Linn County at the Fillmore West in San Francisco, CA from 11/7-10/1968. Art by Lee Conklin, image is # 144 in the Bill Graham/Fillmore series. Medium flat index stock poster is in fantastic near mint (A-) condition; only a slight registration issue (the red pass of ink is ever-so-slightly staggered), a whisper of handling and a touch of surface wear keep this one out of the mint category. A disorienting, almost 3-D-looking example of this ultra-psychedelic Lee Conklin classic.
