The astute workers at the Easton GoodWill store thought that a recent donation was worth investigating. After some research and consultation with experts in the field, their hunch paid off in the amount of $40,600. According to the Baltimore Sun, that is how much an impressionist painting by an artist named Cortes sold for at Sotheby’s auction house. The painting was dropped off as a donation in March, and was recently sold at auction after Sotheby’s confirmed the authenticity of the painting.
