Researchers at Amsterdam's Van Gogh Museum say close analysis of a Van Gogh painting long thought to have been a self-portrait has revealed that it is of his younger brother, Theo. Van Gogh was dependent on Theo who was five years his younger and who died six months after Van Gogh's suicide. Among other things the researchers say the shape of the ear in the painting as well as comparison of it to pictures of Theo demonstrate that the painting is in fact of him. The findings have been published in a 600 page catalogue put together by the researchers at the museum which houses the largest collection of Van Gogh paintings and letters.
