Original 1st printing 13&3/8 x 21" concert poster for the Grateful Dead appearing with the James Cotton Blues Band and Lothar & the Hand People at the Fillmore Auditorium in San Francisco, CA from 11/18-19/1966. 
 
 Art by Wes Wilson, image is # 38 in the Bill Graham/Fillmore series. (BG 38-OP-1 in the Eric King guide)
 
 Medium flat index stock poster is in very good (B/B+) condition; there are tiny pin holes in all four corners and in the top center margin, along with a series of light surface scratches along the left side of the poster that can be seen when the poster is tilted towards a light source, a couple of soft corner-tip bends, a stray edge ding or two, a trace of handling and one or two loose pin-prick spots hiding within the image area, otherwise it is a VERY nice-looking gently-used example of this semi-hard-to-find late-'66 Wes Wilson Grateful Dead poster.
