Welsh Painter

Estimated Worth: $142 Million

Just because you've never heard of Vicari doesn't mean he isn't rich. In 2004, he was Britain's richest living painter, and I doubt his value has depreciated over the years. He amassed his fortune painting portraits of the rich and famous for decades, was once the official painter of the King and Government of Saudi Arabia, and in 2001, he sold a collection of his works, 125 paintings, to Prince Khaled for £17 million ($27 million). He also has three museums in the Middle East that are solely dedicated to his work.
