The museum comprises the more than 1,200 items — rock concert posters, billboards, radios and other memorabilia of the era — that decorate Nakamoto Productions at 907 20th Street. It debuted in the spring of 2000.
According to Newhall, the four most collectible bands' posters are: Cream, The Grateful Dead, The Doors and Jimi Hendrix. When Newhall rediscovered his collection its contents included a rare poster of Cream and The Grateful Dead when the two bands appeared at Memorial Auditorium - the only time the two famed groups played together.
