Original 1st printing 13&3/4 x 22&1/2" concert poster for the Grateful Dead appearing with Lightnin' Hopkins and the Loading Zone at the Fillmore Auditorium in San Francisco, CA on 10/21-22/1966 (poster also advertises the 10/23 Yardbirds/Country Joe & the Fish show). Art by Wes Wilson (with a photo by Herb Greene), image is # 32 in the Bill Graham/Fillmore series. Medium thick flat index stock poster (OP-1 in the Eric King guide) is in superb near mint (A-) condition; only a tiny soft horizontal bend in the extreme top left margin, otherwise it's a VERY bright/sharp 1st printing example of this oft-requested 1966 Wes Wilson Fillmore Dead poster.
