Their Degas is de-gone.

Two Manhattan art dealers are suing an art seller they say is responsible for losing their $3 million Degas sculpture.

In papers filed in Manhattan Federal Court, the Degas Sculpture Project and Modernism Fine Art say they struck a deal with Rose Ramey Long to sell an Edgar Degas sculpture called “The Little 14-Year-Old Dancer” earlier this year.

Long had told the businesses she was buying the works on behalf of a reputable collector who wanted to purchase it and other works they had, including paintings by Willem de Kooning and etchings by Picasso, for a total of $11 million, the suit says.
