She's an antiques dealer. It's her job to buy old things and sell them for more. That's why she was in Goodwill.
I think she likely wanted a payout. Also the terms of the deal are confidential. If she didn't get a payout, I don't see why they would be confidential.
Like all of Europa, Germany and Italy have thousands of years of history together. You are using nationalist terminology that is not even 200 years old to try to grasp 2000 years of history.
At the time king Ludwig I of Bavaria acquired that bust, the nation you identify as "Italy" didn't yet exist. And that was in the early modern. For most of the medieval age, the small territories that today are within southern germany and northern italy were vassals of the same empires.
And while europa sure was almost constantly at war with itself, there was also a lot of trade going on. Who took that bust from whom and if they paid with coin or sword is most likely lost to time.
This just seems to reinforce the notion of "possession is 9/10ths of the law". I'm not saying she should keep it, but it's not obvious who it "belongs" to.
The "King" in front of his name definitely proves that either it or the wealth that was used to acquire it was ill-gotten. All power and wealth of royalty was taken by force.
germans were invading and pillaging a long time before Nazi's came to power and that is not unique to Germany - think Napoleon, so it is more likely than not that it was simply stolen, perhaps repeatedly over a couple thousand years.
Ludwig I of Bavaria never invaded Italy but he did frequently travel there for pleasure, and was known for purchasing antiquities and art.
> so it is more likely than not that it was simply stolen
You really have little rational basis for this belief. Could it have been stolen? Sure, maybe by Ludwig or maybe by whichever Italian sold it to Ludwig, or maybe by the great-great-great-great-grandfather of whoever sold it to Ludwig. But "more likely than not" stolen by Ludwig? Such confidence is merely a reflection of your biases.
I like that they tacked on that it would be on display in Texas for about a year as part of the deal. It kind of, sort of masks that this was probably a sizable financial transaction.
