Monet forgery discovered On 14 February 2008, the Wallraf–Richartz Museum announced that On the Banks of the Seine by Port Villez, attributed to Claude Monet, was a forgery. The discovery was made when the painting was examined by restorers prior to an upcoming Impressionism exhibition. X-ray and infrared testing revealed that a "colorless substance" had been applied to the canvas to make it appear older. The picture was acquired by the museum in 1954. The museum, which will keep the forgery, still has five authentic Monet paintings in its collection.
