The "Salvator Mundi," the world's most expensive painting, which sold for $ 450 million in 2017, is the subject of a $ 1 billion battle between a Russian oligarch and a Swiss art dealer.
While Dmitry Rybolovlev claims that he was scammed into buying works of art, Yves Bouvier claims that he made all his sales legally.
This confrontation is part of the "Bouvier affair," which for several years has cast doubt on the reputation of the art industry.
