Philadelphia public schools go on a hunt for artwork in schools and come up with art worth millions. “The artworks — 1,200 in all, including paintings, sketches, sculptures, murals, tapestries and ancient artifacts — had been donated to the school system or bought for small sums long ago. Over the decades, many of them were taken down when the walls were painted and were put into storage, where they apparently were forgotten altogether. The collection is probably worth tens of millions of dollars, school officials and art experts said.”
