Jason Caffrey, for BBC World Service:

For decades, Mark Landis donated art to museums and galleries across the US. He was feted as a wealthy collector but the pictures were fakes that he had created himself. He was never prosecuted though – he didn’t take payment so hadn’t broken any law.

“It obviously isn’t a crime to give a picture to a museum, and they treated me like royalty. One thing led to another, and I kept doing it for 30 years,” says Mark Landis, one of the most prolific art forgers in US history.

It’s an amazing story. But it’s even better to see Landis in action, in Art and Craft (2014), a documentary about this unique individual.

The BBC’s Jo Fidgen interviewed Landis in early March.
