Black Sabbath and Harry Carmean album art

Few people knew that Harry Carmean did the back cover of Black Sabbath's Heaven and Hell album. Carmean's design for the  album ended up getting a lot of attention and it used for Black Sabbath's national advertising campaign and as well as featured on a billboard towering over the Sunset Strip. Carmean lived for many years in Laurel Canyon which was the heart of the rock and roll industry at the time. He ended up becoming friends with some of rock and roll's finest including Carol King and Mark Volman (of the Turtles), both of whom were his neighbors.
