A New-Zelander art dealer has decided to have a scientific examination carried out on a painting by Paul Gauguin after experts said it was a fake. Tony Martin from Auckland said four pieces of hair mixed with a patch colour would be examined to determine whether they belonged to Gauguin himself. However a laboratory would have to enter in possession of the artist's genes to carry out such test. In addition, there is no certainty whatsoever that these hair fragments did belong to Gauguin.
