Original 1st printing 17 x 22&5/8" concert poster for the Grateful Dead with the Doors, U.F.O. and Captain Speed at the Earl Warren Showgrounds in Santa Barbara on 4/29/1967. Art by John Cushing, image is featured in the Art of Rock on page 268 (plate 3.46). Medium-thin flat/textured stock poster is in superb mint to near mint (A/A- to A-) condition; just the slightest touch of minor handling/surface wear and an ultra-soft bend in the upper right corner, otherwise it's as crisp/sharp as they come. No tapes are available, but you can read all about the Dead's spring 1967 exploits HERE:
