Madame Tussauds is a wax museum in London, England with several branches in other cities around the world. The Beatles were the first rock musicians to be immortalized by the famous London institute in 1964. The figures of the group were and are still constantly updated. The wax figures of the Beatles, as well as ones of boxer Sonny Liston and movie star Diana Dors borrowed from the museum appear along the real Beatles on the cover of Sgt. Pepper's Lonely Hearts Club Band (album).
