A hidden Vincent Van Gogh self-portrait has been discovered on the reverse of a peasant painting by the National Galleries of Scotland.
The extraordinary find is thought to be a first for a UK institution and was discovered when an X-ray was taken of Van Gogh's Head of a Peasant Woman (1885) before the forthcoming exhibition A Taste for Impressionism at the Royal Scottish Academy in Edinburgh.
Hidden from view for over a century, the portrait was found on the back of the canvas of Head of a Peasant Woman, covered by layers of glue and cardboard that are believed to have been applied ahead of an exhibition in the early 20th Century.
