An oil painting donated to a rummage sale for a halfway house for substance abusers in Corpus Christie, Texas, didn't sell at the asking price of 50 cents. So after the sale the house director decided to research the signature on the painting. He learned it was the work of Alfred de Breanski, a 19th century British artist whose paintings sell for hundreds of dollars. The painting was later auctioned for $19,000. Readers, it pays to check out those old paintings.
