The last remaining painting by Leonardo da Vinci in private hands, Salvator Mundi ("Savior of the World"), will be sold at Christie's in November with a pre-sale estimate of USD $100 million. Though it was only determined to be a Da Vinci six years ago, the portrait of Jesus has an amazing backstory.
Salvator Mundi was sold at Christie's in 1958 for only USD $60. Following a meticulous restoration and scholarly research establishing its status as a da Vinci, the work returned to public auction in 2013 at Sotheby's, where it was purchased by the controversial Swiss freeport owner Yves Bouvier for USD $80 million. Bouvier then flipped the work to his client, the Russian oligarch Dmitry Rybolovlev, for USD $127 million. The work subsequently became embroiled in Rybolovlev's allegations against Bouvier, with the Russian investor claiming that we was defrauded of USD $1 billion by the Swiss businessman.
