Article Photos: German art hoard held unknown Chagall, Matisse 6/10

A painting of Marc Chagall is projected on a screen during a news conference in Augsburg, southern Germany, Tuesday, Nov. 5, 2013, on the art found in Munich. A hoard of more than 1,400 art works found last year at a Munich apartment includes previously unknown pieces by artists including Marc Chagall, German investigators said Tuesday, adding that they face a hugely complicated task to establish where the art came from.
