Batman: Legends of the Dark Knight #142 p.9

After the Joker had been kidnapped from Arkham Aslyum by mysterious individuals, Batman searches through his cell for clues as to the identity of the individual as he's being heckled by Riddler, Scarecrow and Mad Hatter from their own cells.

From "The Demon Laughs Part" story, this storyline marked both Jim Aparo's final published art for a Batman story and final comic work in general before retiring from the industry. Aparo provided the original pencils before being inked over by John Cebollero. As far as my research led, the only other published art after this by Aparo was the alternate unused page of Batman finding Jason Todd alive in "Death in the Family." Makes for a hell of a first Aparo Batman page to own with it featuring Batman prominently along with appearances by Riddler, Scarecrow and Mad Hatter in their regular identities
