LOL, museum curators around the world have to take valium after they read that.
That is sure vague. I just watched the DVD "The Rape of Europa" tonight, about the industrial sized theft of art by the Nazis and Soviets, also with a lot of coverage of what was lost in the bombings and fires.
I highly recommend it, it is amazing to see the worlds great masterpieces being handled and put into army trucks, laying on floors where they were tossed, and so on.
They should have taken it to Antiques Roadshow!
