A Hidden Self-Portrait of Van Gogh Was Found Behind The Artist's Other Work

Vincent Van Gogh often used both sides of the canvas because he was low in money and over the time the reversed works were discovered here and there. Recently the National Galleries of Scotland found the another of the gems.

"Moments like this are incredibly rare," Frances Fowle, senior curator of French art, said in a statement. "We have discovered an unknown work by Vincent van Gogh, one of the most important and popular artists in the world."

The discovery occured during an X-ray of an 1885 painting by Van Gogh, Head of a Peasant Woman.

"Hidden from view for over a century, the self-portrait is on the back of the canvas with Head of a Peasant Woman and is covered by layers of glue and cardboard," the museum said in a statement on Thursday.
