It’s curious that they’ve got such a precise value on the painting should it prove to be a Van Gogh but researchers plan to use a hair embedded deeply in the paint on a disputed painting to determine if the DNA is related to current Van Gogh descendants:

If confirmed a Van Gogh, the painting could fetch a value of £39 million and make Cologne art collector Markus Roubrocks, its owner, a multi millionaire.

The bright painting of a vase of multicoloured peonies resting on a wooden floor was discovered in a Belgian attic in 1977, and since then debate has raged in the art world whether it is the work of the Dutch master.
