Over the past twenty years, dozens of paintings from a private collection of Russian and Ukrainian modern art have been sold to museums and private collectors around the world. The collection is said to include over 200 oil paintings by revered avant-garde artists like El Lissitzky, Alexandra Exter, and Liubov Popova. It’s one of the biggest collections of its kind in the world. But there are growing suspicions that the story behind the provenance of the paintings in the collection is made up, and that many of them could be worthless fakes. The BBC follows the art detectives and scientists, trying to get to the truth about the Zaks collection and its mysterious owner.
