Portraits of Vincent van Gogh

A previously unknown self-portrait of Vincent Van Gogh has been discovered behind another of the artist's paintings, the National Galleries of Scotland said Thursday.

For decades the bright-eyed boy in the photograph was believed to be the legendary artist Vincent Van Gogh at the age of 13. But experts revealed Nov. 29 that the picture is most likely not the Dutch "Sunflowers" painter but his brother Theo, who was 15 at the time.
