Special colorful Campbell’s tomato soup cans are now available at some Target stores. Four different labels inspired by the famous Andy Warhol paintings are available on new cans. For 75 cents you can buy the can, open it carefully from the bottom to preserve the label, pour out the soup and eat it, then save the limited-edition can. It may go up in value, although 1.2 million cans are being sold. A similar promotion was done in 2004 and 2006 and although we saved the empty cans, we have not seen any sold for high prices. But they do make a puzzling display on a kitchen shelf.
