The Sterling and Francine Clark Art Institute in Williamstown, Massachusetts maintains a photo and clippings file containing close to a million items that were used to study art in the early part of the 20th century. The Clark has recently digitized a
sad selection of these images because they are the only surviving evidence that these paintings ever existed. The originals have all been lost, destroyed in Europe during World War II.
