Infrared scans have revealed Norwegian artist Edvard Munch was the author of hidden graffiti on his 1893 painting The Scream.
The inscription near the top left corner reads kan kun være malet af en gal mand , which translates from Danish as can only have been painted by a madman and was thought to have been later added by vandals.
Following years of speculation, the National Museum of Norway has confirmed that the small and barely visible sentence was actually by the artist himself in about 1895.
Munch made the inscription with a pencil after a medical student said The Scream was the work of a mentally disturbed individual.
