What was the (children's?) Tv show that had a reoccurring character who was a rich art thief, he usually wore all white suits? iirc he was actually a fraud art thief, but had this kid believing him. In one appearance, he finds some paintings and everyone is upset because they look cheap, but the thief later dabs them with water and a masterpiece is underneath.
Thanks!
