The Dutch Restitutions Committee has rejected the claim of two Jewish art dealers for all but one of 189 works in the country’s national collection. The committee did return one work, Ferdinand Bol’s Man With High Cap, but was unable to find enough evidence to return any of the other contested works. “Ownership of most of the works has not proved very probable,” the Dutch Restitutions Committee said in its recommendation, published late yesterday on its website. “During the occupation, the Katz brothers often acted as middlemen and intermediaries for German buyers.”
