CARY — A man who bought an oil painting at a Goodwill store in Cary says he thinks his find could be worth $1,600.

The News & Observer of Raleigh reports that Tony D’Amico recently bought the seascape of waves crashing against rocks for $7.

D’Amico says he paints in his spare time and noticed the painting’s signature “Uwe” and handmade frame. D’Amico says he tracked down the painter, California artist Uwe Werner, and described the painting to him.

Werner said he was sure it was one of his early pieces and was an original. The artist says he thinks the painting, called “Lone Gull,” could be worth as much as $1,600.

D’Amico says he won’t sell the piece. He says it’s an inspiration for his own artwork.
