Discover how the notorious art forger Han van Meegeren tricked the world— and the Nazis— with his counterfeit Vermeer paintings.

Uploaded 06-04-20

--

It was one of the strangest trials in Dutch history. The defendant in a 1947 case was an art forger who had counterfeited millions of dollars worth of paintings. But he wasn’t arguing his innocence— in fact, his life depended on proving that he had committed fraud. Who was this artist, and why was he on trial for his life? Noah Charney investigates the notorious Han van Meegeren.

Lesson by Noah Charney, directed by Hype CG.
