Van Gogh's self-porter detected: It was hidden behind another painting

Experts in Scotland's National Gallery made the discovery when the telajo was X-rayed in front of an exhibition.

The hidden export was covered by sticky layers and cardboard on the back of a previous work called the head of a peasant woman.

The old consultant of the Lesley Stevenson Gallery said she felt <x0-thermit” when she found the artist “looking to us”.

She said: “When we first saw X-rays, we were certainly extremely excited.

This is a significant discovery because it adds to what we already know about Van Gogh's life. ”

The Dutch artist often reused canvass to save money, turning them and then working on the other side.
