Previously, a self-portrait of the famous painter, Vincent Van Gogh, was found partly visible in an X-ray image reverse side of his own painting: Head of a Peasant Woman, present in the National Galleries of Scotland. Van Gogh was poor at the time he was painting his portrait and he had been using both sides of his canvas but occasionally, after a few years, a few of his back-side paintings got hidden in cardboard and glue.

As the museum was preparing an exhibition on impressionism, a style or movement in painting originating in France in the 1860s, they X-rayed some paintings, and they soon found the hidden 1885 portrait.

It’s not known if people can fully uncover the hidden self-portrait, or even if it’s possible, but either way, you can still see an X-ray image showing the ancient portrait which is said to be in the exhibit that’s coming soon.

The museum has the image as a man with a beard wearing a brimmed hat and neckerchief tied at his throat. The man has a harsh stare to the viewer, the right part of his head in shadow and his left ear visible.
