A little-known painting by Marc Chagall has taken the international spotlight after a small museum in London revealed over the weekend that it has purchased the work at a bargain price. Chagall's "Apocalypse in Lilac, Capriccio" (1945) was purchased in October at a Paris auction by the London Jewish Museum of Art for 30,000 euros (approximately $43,300), according to reports. Some experts believe the work is worth more than $1 million.
