If the sale was legitimate sure. But there is a long, proven history of fraudulent sales and straight theft. In those (numerous) instances would it not behoove the recipient to return them? There are some people here saying “the people who made them are dead”. Which I imagine is an argument for “nobody actually owns them”. Which is a myopic view. The cultural heritage of a region should be able to be enjoyed by the people of that region. Imagine if major artifacts of American, or British (or wherever you are from) history were lost to another far away land and you had no opportunity to marvel at them, how might you feel? That said, there is something to the notion of borrowing and “tours” of artifacts, so people of the world can also enjoy them.
