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 partially restored to excellent (B+) condition; there are a series of ultra-tiny pin holes in each corner and around the outer margin area that have been filled (although a couple of holes still remain), along with a 2" vertical tear through the "T" of "Toronto" that has been professionally sealed and camouflaged (I could only really see it by holding it underneath a bright light), plus a couple of VERY tiny surface repairs and minor touch-ups here and there- but all told, I have to say this one is REALLY sharp-looking... one of the better specimens I have encountered.
An overall SUPERB example of the semi-elusive BG 74. Check out a portion of the Dead's 8/4 set HERE:
