Originally known only by his alias, the Penguin first appeared in Gotham City as a skilled thief, sneaking a pair of priceless paintings (valued at $250,000 in 1941 dollars) out of an art museum by hiding the rolled-up canvases in the handle of his umbrella. The Penguin later used the stolen paintings as proof of his underworld acumen to a local mob boss, who allowed him to join his crime family. With the Penguin's planning, the mob pulled off a string of ingenious heists. The "be-monocled bird" and the mobster eventually fell out, leading Cobblepot to kill him with his umbrella gun. The Penguin became the leader of the mob and attempted to neutralize Batman by framing him for the theft of a statue which Penguin, himself, had stolen. As part of the plot, Penguin actually already owned the statue and was framing Batman and Robin to commit insurance fraud. The Penguin's plans were eventually prevented, but the bandit himself escaped.
