The Times reports on a painting that the Wallraf-Richartz Museum and Foundation Corboud in Cologne has displayed as a Monet original is a fake
Researchers used X-rays, infrared technology and paint tests to examine the work, along with 70 others.
It was noted that the painter's name was retraced so that it would be darker. “This does not happen with an original. The artist just throws his signature on to the canvas. Also, the painting was made over a drawing that was clearly not in Monet's style,” a spokesman said.
He added that a colourless substance had been added to the canvas, to make it appear older. The original was produced in 1894.
The painting will remain on display, although the museum said that it would be clearly marked as a fake.
