Original 1st printing 14 x 21&1/4"  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-thick smooth index stock poster is in near mint to excellent (A-/B+ to B+) condition; there are a couple of tiny pressure creases in the upper and lower right corner tips, along with a tiny hairline bend in the bottom left corner and a nearly-invisible handling ding or two hiding within the image area, otherwise it is an absolutely GORGEOUS example of this strange-looking late-1968 Grateful Dead/QMS poster from the Fillmore.
