This is from Mad Magazine. April 1980.
The print might be too small to read, but it's a comic about a vampiric pop-star manager that shows John Revoltya around his house. Revealing to him that he keeps rooms full of clones of his stars. Even clones of Revoltya.
(Also interesting that April 1980 is when The Shining was released).
Then there's this scene from A Hard Day's Night.
