World's Finest Comics #52

There are only seven people in Gotham who are insured for $1,000,000. Artist Jan Marki believes he should also be insured for $1,000,000, but the insurance company turns him down, believing his talent is not worth that much. Marki intends to prove himself, but instead injures his hands so he can no longer paint. Marki then seeks revenge on the insurance company by trapping the other $1,000,000 insurees, including Bruce Wayne, in a booby-trapped mansion. Batman then utilizes the skills of the stars to overcome the booby-traps to escape and capture Marki.
