Batman Annual #12 CGC 9.6 Kaluta Cover DC Comics - 1988

Bruce Wayne has been invited to a "murder party" at the grotesquely designed Slade Estate in New York by the current owner of the house, Monica Slade. Unbeknownst to her, the grounds of the crumbling mansion will be the scene of Batman’s hunt for two foes--one a ruthless killer, the other something that may not even be human.
