MILAN (AP) — Italian authorities have recovered three 15th_century paintings seized from an Italian-Luxembourg noble family during World War II.

Authorities on Monday unveiled the paintings, all by little-known artists, at the Brera Art Gallery in Milan, where they are currently housed.

The works were among property seized from the Borbone-Parma family after Italy entered World War II, making Luxembourg an enemy state and allowing seizure of properties under wartime law. Many of the family's treasures were recovered by the U.S. military after the war, but not these paintings.

Investigators for the Carabinieri state police unit charged with protecting cultural heritage only recently traced the works to two families in Milan who had inherited them. The works, which have not been valued, are in state custody after no living descendants could be traced.
