I see what you are saying - and that is an excellent insight. I did not ask myself about how that painting turned up where it did, but now that you mention it ... it has a real postWW2 ring to it.
I shall get hold of a copy of that documentary, if I can.
I also recommend a novel by Douglas Boyd, "The Fiddler and the Ferret". It is a thriller written by an historian of WW2 France, and the plot makes a lot of allegations about how art works stolen by the Nazis ended up in other hands. Fiction of course ... but interesting to read, and possibly based on fact.
Go on line and see if your library has the DVD to check out, or get them to order it from one of the other branches, it is usually a free library service.
Another good book is “ The Forger’s Spell” by Edward Dolnick-true story of Vermeer, Nazis, and the greatest hoax of the 20th century.
Fast and fascinating read. Dolnick references “The Rape of Europa”.
