"The Kaleidoscope was located in the Hollywood area at Sunset and Vine and was no doubt the premier rock venue in the Los Angeles area. The posters used at the Kaleidoscope were all produced in a round format and are unique as a series. Many of the big bands of the era, such as The Grateful Dead, Canned Heat, Jefferson Airplane, James Cotton, and the Doors played here. The original poster was printed on white index stock and measures approximately 18&#8243; in diameter.  "
