A French innkeeper has a dream of hanging a real Van Gogh painting in his inn in the room where the artist died. He knows the painting; now he’s trying to find a way to buy it. “As Sotheby’s estimates the painting’s value from $28 million to $35 million, and bidders may drive the price higher, Mr. Janssens is now trying to raise money through private donations and from an appeal to van Gogh lovers through a Web site (vangoghsdream.org).”
