Lupin vs The Man of Two Faces

To cover the dinner bill for the President of France, an auction of artworks in storage at the Louvre is held, with an extemporaneous piece by Lupin I going on the block. It goes to Nai Baba, Arabian village chieftain and oil millionaire. It gets transported under heavy guard, but Zenigata knows that Lupin will try to take it.
