Portrait found under Van Gogh painting

AMSTERDAM, Netherlands, Oct. 31 (UPI) -- An Amsterdam museum employee has found what may turn out to be the first self-portrait painted by Dutch master Vincent Van Gogh.

Aukje Vergeest, of the Van Gogh Museum, found the painting underneath a 1886 painting of a park that she had X-rayed, Expatica reported Monday.

It is unclear at this point, however, if the portrait is authentic. The two paintings can be separated using an expensive, digital technique, Expatica said.
