In 2017, the world's most expensive painting sold for a record $450 million. Twelve years earlier, it went under the hammer for $1,175, lacking the description: 'the only privately-owned Leonardo Da Vinci'. In this deeply-researched book, historian Yuri Felshtinsky traces the nebulous connections behind this miraculous increase in value. His story is as complex and intricate as Da Vinci's Mona Lisa and leads from the Kremlin to Donald Trump via oligarch Dmitry Rybolovlev, art dealer Yves Bouvier, Freeports and the world's most expensive private residence, located in Florida.
