An orphan in the larger picture

I have been reflecting on the announcement of fragmentary Greek pots to Italy. And it strikes me that a fragment acquired by the J. Paul Getty Museum in 1984 and its relationship to other fragments of the same Athenian red-figured cup probably give us a clue.

The significance lies in the list of donors and former owners who held the fragments.

And have any pieces from the same cup been returned to Italy in the latest batch of material?
