A rural Maryland Goodwill store received a donation that turned out to be a French Impressionist painting worth more than $40,000, reports the Associated Press.

Store employees suspected the painting, donated in March, to be valuable and asked the manager, Terri Tonelli, to take a look at it. She Googled the artist’s name, Edouard-Leon Cortes, and realized his works had sold for prices nearing $60,000 in recent auctions.

The painting, called “Marche aux fleurs,” features a Parisian street scene and was probably completed in the early 20th century. It sold for $40,600 at a recent Sotheby’s auction.
