Golfe, mer, falaises vertes (est. $130-180K), by Pierre-Auguste Renoir, was scheduled to be sold at Dorotheum in Vienna; however, it appears that three gentlemen walked into the auction house and decided they really wanted it - right now, so they took it. Now any theft is a bad thing, but my question is: why did they take that Renoir? Maybe they liked the signature?
