MILWAUKEE (AP) — “Red Nose” just meant a reindeer named Rudolph to Karen Mallet until she bought a print by that name for $12.34 at a Goodwill store in Milwaukee. It turned out to be a lithograph by American artist Alexander Calder worth $9,000.

Mallet’s good fortune is at least the fourth time in six months that valuable art has turned up at Goodwill, where bargain-hunters search for hidden treasure among the coffee cups, jewelry, lamps and other household cast-offs.
