Original 1st printing (no ink scuffing in "Warren") 17 x 22&5/8" concert poster for the Grateful Dead appearing 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) and is part of the Jim Salzer Presents series.

 Medium-thin flat/textured ("pebbled") stock poster is in good to very good (B to B/B+) condition; there are multiple pin/tack holes in all four corners with a couple of tiny wedge tears and a small nip/chunk out of the lower right margin, along with a light to moderate amount of handling wear/creasing, a few thin bends and tiny pin-prick spots hiding within the image area and a couple of soft stains/minor discolorations in the outer border area, otherwise fine. 

 No tapes are known to exist, but you can read all about the Dead's spring 1967 exploits HERE:
