The painting, called "Rembrandt Laughing," was estimated to sell at auction for $3,100. A bidder recognized it as an original Rembrandt self-portraint and bought it for $4.5 million. A bargain, considering it is worth about ten times that amount. It was painted by the artist in 1628, when he was in his early twenties.
