The Greatest Da Vinci Deal: Trump's Election Campaign and the Strange Case of a Masterpiece, a Sheikh and a Piece of Florida Real Estate

In 2017, Salvator Mundi by Leonardo Da Vinci set a world record by selling for $450m, the highest ever-paid for a painting.

The sale was highly controversial, however, not least because the buyer was anonymous. Although it was the only Leonardo known to be owned privately, the image was only thought to be part-painted by the master and it was only rediscovered in 2005 at a Pennsylvania auction. Historian Yuri Felshtinsky shows this was only a small detail in its convoluted, far stranger history, which involves Donald Trump's election campaign, Saudi Arabia, Switzerland, Monaco and a Russian billionaire.
