Original 1st printing 11&1/2 x 26" concert for the Grateful Dead appearing with the Hindustani Jazz Sextet (featuring Hari-Har-Rao and Don Ellis) and Big Brother & the Holding Company (with Janis Joplin- VERY early gig for her) at the Fillmore Auditorium in San Francisco, CA on 7/14/1966.
Art by McCallum, image is featured in the Art of Rock book on page 185 (plate 2.182), this is a hand-lettered ticket outlet poster (written in pen in the bottom margin) that has additionally been HAND-SIGNED (in black sharpie) by GD drummer Mickey Hart (this show was over a year before he joined, but it probably didn't occur to either the person who obtained the autograph, or Mickey).
Medium-thick flat vellum stock poster is in good to very good (B to B/B+) condition; a series of stray pin/tack holes (top/bottom center margins ans on the "Hi" of "Hindu", a light amount of handling/creasing, a series of tiny diagonal creases in the bottom left corner tip, a 1" diagonal bend in the top right corner, a few stray surface dings/tiny stress bends, a 1'vertical bend in the top margin and as mentioned, "Tickets On Sale Here" has been hand-written in the bottom margin, otherwise fine.
VERY EARLY and SCARCE G.D. Fillmore poster from one of only a few non-Bill Graham sponsored events held at the Fillmore (show was put on by Calliope Company).
