Thanks, Albion, for the additional info. I am aware of the controversy (and confusion). I wonder if the originals were really lost during WW2 or are hanging in someone’s home. So much art disappeared during the war.
I had heard a story about the Louvre, that when bombing became a possibility, the art was distributed to private citizens, and after the war, all of it was returned. While “all” seems unlikely, “most” seems possible. Perhaps France differed from Germany in this regard, since Germany was having essentially a civil war after their defeat in WWII.
