A painting that was lost in the Holocaust and resurfaced in 2006 was auctioned in London on Friday for $92,350.
Polish authorities working to return Nazi-looted art brokered a deal between the current Latvian owner and the descendants of a Polish Jew who once owned the painting.
A boy, in profile, singing, in a feigned oval is an oil, painted in about 1620 by Dutch painter Pieter de Grebber.
London dealer Johnny Van Haeften bought the painting, saying he found it very appealing, and that he was glad the heirs would have a share of the proceeds.
A few years ago, Van Haeften returned a portrait by Adrien Brouwer to Poland after learning it had been stolen.
Abe Gutnajer, an art dealer in Warsaw, bought the de Grebber painting in 1917, but it disappeared from his home after he was sent to the Warsaw ghetto.
The Nazis corralled about 450,000 Polish Jews in the Warsaw ghetto beginning in 1940. Many were killed by Nazi troops, including Gutnajer.
His son, Ludwik, is now dead but he left a widow, Eve Gutnajer-Infanti of Philadelphia, and two children, Stefan and Krystyna.
They have agreed to split the proceeds with the current owner, but the terms of the split have not been released.
Poland's foreign ministry helped broker the deal after auctioneers Christie's found the painting listed on the Art Loss Register of work owned by Polish residents that disappeared during the Second World War.
