Original 1st printing 13&7/8 x 20&3/8" concert poster for the Jefferson Airplane and the Grateful Dead appearing with Luke & the Apostles (not listed) at the O'Keefe Center in Toronto, Ontario, Canada from 7/31-8/5/1967.
Art by James H. Gardner with photos by Herb Greene, image is # 74 in the Bill Graham/Fillmore series.
Medium-thick flat vellum stock poster has been professionally restored to excellent (B+) condition; all four margins/corners have has paper fills along with a bit of hand-done touch-up to some of the lettering in the lower left/right margins, plus there is a bit of light handling/surface wear and a few minor rippled areas to the paper, but for the most part, it is a fine-looking example of this set-stopping Bill Graham poster.
VERY, VERY nice ORIGINAL specimen of the elusive BG 74. Check out a portion of the Dead's 8/4 set HERE;
