This photo provided by the Kroeller Mueller Museum in Otterlo, Netherlands, Tuesday, March 20, 2012, shows a painting entitled "Still life with meadow flowers and roses" by Vincent van Gogh. The Kroeller Mueller Museum says new X-ray research has finallyput beyond doubt that "Still life with meadow flowers and roses" really is by Van Gogh. It has also uncovered in greater detail an art school study by Van Gogh of two wrestlers concealed on the same canvas and invisible to the naked eye.
