Original 1st printing 14 x 22&1/2" concert poster for the Grateful Dead 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 (and SIGNED in black sharpie by) Wes Wilson (with a photo by Herb Greene), image is # 32 in the Bill Graham/Fillmore series. Medium flat index stock poster (OP-1 in the Eric King guide) is in superb near mint (A-/B+) condition; only the slightest trace amount of handling/light creasing along the top margin and a stray pinch ding or two, otherwise it's a VERY crisp/sharp SIGNED example of this iconic pre-beard Jerry Garcia image.
