Supporters of the Detroit Institute of Arts have offered to donate $330 million to help pay a portion of the city’s bankruptcy debt and save the museum’s finest works from being sold at auction. The donors would like the funds to go to retirees, whose pensions may be cut by as much as $3.5 billion. In exchange, the Detroit Institute’s collection would be protected in any bankruptcy settlement. A statement e-mailed to the U.S. District Court in Detroit said, “All recognize that if these two goals can be accomplished, a third absolutely critical goal of facilitating the revitalization of the city in the aftermath of the bankruptcy will be greatly advanced.”

Detroit filed for bankruptcy in July 2013 and the city is currently over $18 billion in debt. Following the filing, Kevyn Orr, Detroit’s emergency manager, asked Christie’s to appraise the 2,781 city-owned works housed in the Detroit Institute of Arts. The auction house estimated the works to be worth anywhere from $452 million to $886 million.

The Institute has opposed any sale, stating that its art is held in a charitable trust and cannot be part of any auction to help pay Detroit’s substantial debts.
