With an estimated net worth of about $10.7 billion in 2016, Abramovich is among the most deep-pocketed art collectors in the game and is believed (confirmation is always a tricky business) to have snapped up quite a few trophy artworks at auction over the years, including a Francis Bacon triptych for about $86 million and a Lucian Freud for $33.6 million. Zhukova, meanwhile, runs the formidable Garage Museum of Contemporary Art in Moscow, which opened its new Rem Koolhaas-designed headquarters in June 2015. The Garage recently started an outpost in St. Petersburg.
