Five artworks will be removed from public view at the Kunsthaus Zurich museum in Switzerland in order to investigate whether they were looted by Nazis during World War II. The paintings are by Monet, van Gogh, Gauguin, Courbet and Toulouse-Lautrec, and come from the Bührle Foundation, which has been working with a provenance researcher for many years to determine the ownership history of the collection. Here's more from NPR.
