According to the New York Post:
An award given to magician David Copperfield disappeared into thin air, the old-fashioned way, from his Midtown penthouse. Copperfield recently received a “King of Magic” honor, bestowed by the Society of American Magicians, at a reception at his apartment. After an evening of toasts, cake and champagne to celebrate - (snip) Copperfield followed the crowd out the door and enjoyed a late dinner on the town. But when he got back home -- presto chango! -- he discovered his front door was wide open, and the cherished plaque was nowhere to be found. The magic man is now offering a $50,000 reward for its safe return.
I'm not accusing anyone of anything, but where was David's favorite "masked magician" at that time? ;-)
