Apulian hydria returned to Italy

Last month Christie's was reported to have returned eight antiquities to Italy [press release]. This initiative appeared to be a new one but it now appears that the objects may relate to historic cases. For example, the returned Apulian hydria attributed to the Varrese painter appears to be the one identified at the April 2015 Christie's sale [see Looting Matters] by Dr Christos Tsirogiannis from an image in the Becchina archive. 

One wonders why this historic information as well as Tsirogiannis' contribution has been omitted. Back in 2015 I commented on why the hydria's history (and the histories of its companions) had not been spotted by the auction-house.
