Two Manhattan art dealers---formerly with Knoedler Gallery---have been accused of selling fake paintings by abstract expressionist Robert Motherwell, according to the Dedalus Foundation, a group in charge of authenticating the artist's work.

Court papers allege that Ann Freedman, who was a longtime president of Knoedler, and former Knoedler salesman Julian Weissman, received 7 forged Motherwells from a Long Island woman. They then allegedly created provenances for the works.

Weissman is being cross-sued by the foundation for $9 million-plus for "negligent misrepresentation" of one of the works that he sold to Killala Fine Arts, for $650,000 in 2007. Killala has sued the foundation for failing to include the work in the forthcoming Motherwell catalogue raisonne.
