Aug. 27 (UPI) — A painting looted by Nazis from a Jewish Art dealer 80 years ago has been seen on the website of an estate agent selling a house in Argentina.

The painting Portrait of a Lady (Contessa Colleoni) by the late baroque portraitist Giuseppe Ghislandi was seen in a photo hanging above a sofa in the living room of a house in a seaside town near Buenos Aires.

The Dutch newspaper AD reported that the painting is featured in a database of lost art.

“There is no reason to think this could be a copy,” said Annelies Kool and Perry Schrier of the Cultural Heritage Agency of the Netherlands, who reviewed the images for AD.

The artwork is among hundreds looted from an art dealer who helped Jews escape during the war, Jacques Goudstiker.

More than 1,100 paintings were brought up in a sale by senior Nazis after he died after falling in the hold of the vessel and breaking his neck.

After World War II, some works had been recovered in Germany, but Portrait of a Lady was not among those.

AD’s investigation found wartime documents suggesting the painting was in possession of Friedrich Kaidgen, an SS officer and senior financial aide to Goring.

Kadieng died in 1979, and as a U.S. file seen by AD said he “Appears to possess substantial assets, could still be of value to us”.

The paper noted it made efforts to speak to his two daughters about the missing artworks. A reporter was dispatched to knock on doors where they believed someone was home, but no one opened the door.

“There was certainly someone at home; we saw a shadow moving in the corridor, but no one opened,” the journalist, Peter Schouten, reported.

AD said all attempts to speak to the sisters since finding the photo had failed, with one reportedly telling the paper: “I don’t know what information you want from me, and I don’t know what painting you are talking about.”
