Paris’ Louvre is asking for donations to help it buy a painting by French 17th-Century artist Georges de la Tour. De la Tour’s portrait of St. Thomas, painted between 1625 and 1630, has been put up for sale for $6 million by the Sovereign Military Order of Malta. “It is our duty and not simply a desire to acquire this painting,” Louvre Director Michel Laclotte said at a Monday news conference. “We want to do our best to display the great French painters.”
