That's why I was talking about tangible property. A bank account is another matter altogether, obviously.
If some old NAZI had a Reubens hanging on the wall that he looted from some family during the War, I say give it back. In the famous case of Abe Simpson and Mongomery Burns Tontine vs Baron von Wortzenberger the courts rightly decided that since Simpson, Burns and the other members of his unit had personally looted the Flying Hellfish Treasure, they would be required to return the artwork to the idolent Baron even after decades had passed.
But that is not the case here. The British Museum was paying a party many times removed from the theft the going rate (at the time). They did not do anything wrong, here.
The Nazis wiped out the business.
No doubt there were bank accounts, but the family lost track of them. I keep my eye on all this stuff.
Ahh, citing a cartoon for precident. You sure are taking these claims seriously.
