New Van Gogh and Not a Van Gogh

I mentioned this
Vincent van Gogh painting last year when experts were unsure about the authenticity of the work. It turns out that it isn't a Van Gogh painting, nor is it a forgery.
"Gerard Vaughan, insisted after tests by the Van Gogh Museum in Amsterdam concluded the oil-on-canvas work was not painted by the Dutch master, as believed. But Dr Vaughan made the point that it was not a forgery. "There is no evidence to suggest that someone produced this picture at a later date to pass it off as a work by Van Gogh." Sydney Morning HeraldThe
National Gallery of Victoria in Australia says that it's still a "fine and interesting" painting and it will still be hung in the gallery.
But while one Vincent van Gogh disappears, another appears!

An 1889 drawing by the Dutch master of Wild Vegetation (pictured to the right) was suspected of being a copy of one of his paintings. It has now been discovered under "The Ravine" painting which is in the
Museum of Fine Arts in Boston.
I couldn't find a picture of the x-rayed painting online, but the drawing will be on show at the Van Gogh Museum in Amsterdam from the
13th of July through to October 7.
The Washington Post writes more about the work.. "
Meta Chavannes, a conservator at the Boston museum, said she revealed "Wild Vegetation" by "pure chance" while compiling information for some visiting scholars. Chavannes said she became a "little bit obsessed" with the painting, and took the X-ray with her when she went home to Holland on vacation. There, she showed it to Louis van Tilborgh, a Van Gogh Museum curator.">>
