Pink Floyd ‎– The Division Bell (EMI, 1994)
The long-time collaborator of the Floyd, Storm Thorgerson, was responsible for the cover art. Drawing inspiration from the book by American mathematician Norbert Wiener "The Human Use of Human Beings" from 1950, he erected two large metal heads in a field near Ely Cathedral. The statues were positioned to face one another closely, and he photographed them in profile, creating the illusion that not only were they looking into each other's eyes but also speaking to one another, thus forming a third face in the eyes of the observer when viewed head-on. The two sculptures were positioned by Keith Breeden, and built by John Robertson. Ely Cathedral is visible on the horizon in the background between the mouths of the two faces. Currently, the sculptures are housed in the Rock and Roll Hall of Fame in Cleveland, Ohio. [source Wikipedia]
