The painting is of Ria Munk, who committed suicide in 1911 at the age of 24 because of an unhappy love affair. Her mother, Aranka Munk, asked Klimt to paint her posthumously, which he did, three times. Authorities in Linz have until now said there was no proof that the portrait hanging in the city’s Lentos Museum is the one looted by the Nazis from Munk’s villa in Bad Aussee.
