A very rare promotional poster for The Grateful Dead made by Warner Bros. circa the release of their March 1967 debut album. This 22′ x 28′ poster is printed on thin stock, and is in overall near excellent condition, with staple holes in the four corners, some tape pulls on the back, and some light horizontal creasing from having been rolled and creased at some point in the distant past. One of only three we’ve seen in the past 30 years.
