The National Galleries of Scotland has discovered what is almost certainly a<br />previously unknown self-portrait by Vincent Van Gogh.<br />Hidden from view for over a century, the self-portrait is on the back of the canvas<br />with Head of a Peasant Woman and is covered by layers of glue and cardboard.<br />NGS experts believe these materials were applied ahead of an exhibition in the early<br /><br />twentieth century. Van Gogh often re-used canvases to save money. However,<br />instead of painting over earlier works, he would turn the canvas around and work on<br />the reverse.
