Original 1st printing 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 excellent to near mint (B+ to B+/A-) condition; aside from a pair of nearly-invisible moisture droplets in the lower right portion of the ticket outlet strip (you have to tilt the poster in order to see them) and an ultra-soft horizontal bend extending from "Francisco" to the outer right margin, this example is just about as clean as they come.

 GREAT-looking original 1st printing 1968 Dead Fillmore poster with a very trippy/weird Lee Conklin design.
