Stephen King's Misery
(1987) had a novel within the novel, Misery's Return
by Paul Sheldon. Below is the cover of the Viking hardcover, an image repeated for the cover of the 1988 Signet paperback. However, opening the Signet paperback revealed another cover (above). It featured an inside joke, showing King himself in the romance cover. This painting has been used on products, including a throw pillow and a T-shirt.
