Mugrabi owned the world's largest collection of paintings by
Andy Warhol, which are now owned by his sons. His art collection included works by Renoir, Picasso, Rodin, Ernst, Daumier,
Damien Hirst,
Jeff Koons, and
Jean-Michel Basquiat in addition to 800 Warhols. He also owned the largest collection of
Philippe Pasqua's paintings. The Mugrabi art is stored in Zurich and near Newark, New Jersey. Mugrabi's first purchase was a Renoir landscape, bought in 1982 for $121,000 on the advice of Deitch. The Mugrabis say they base their collecting model on
Charles Saatchi, although he purchased multiple works of many artists and the Mugrabis collect only a preferred few. In 2008, the
Wall Street Journal reported on how the Mugrabis were said by several art dealers to be "doing whatever they can to keep Warhol prices high, including occasionally overpaying – or overcharging – for the artworks." In 2008, he bought Warhol's
Detail of the Last Supper (Christ 112 Times) (1986) for $9.5 million. He purchased Warhol’s
Men in Her Life (1962), a painting based on an image of a young
Elizabeth Taylor between husbands, for $63.3 million in 2010, the second-highest price paid for a Warhol at the time. At a 2012 Sotheby's auction, he acquired Warhol's
Double Elvis (Ferus Type) (1963) for $33 million. At a
Christie's auction in 2013, he sold
Coca-Cola (3) (1962) to
Alice L. Walton for $57.2 million. In 2013, Mugrabi set a record for the most expensive work by a living artist, when he paid $58.4 million for Jeff Koons’s
Balloon Dog (Orange) from
Peter M. Brant's collection at Christie's. ==Losing to Madoff==
