One of the pieces seized from an as yet unnamed Manhattan gallery is a Paestan lekythos attributed to the Asteas-Python workshop. It has a stated collecting history:

• Swiss private collection
• Royal-Athena Galleries (1987-1988)
• John Kluge private collection
• Patricia Kluge private collection, Charlottesville, Virginia (1990-2010)
• Royal-Athena Galleries: One Thousand Years of Ancient Greek Vases II ... Featuring the Patricia Kluge Collection (2010) no. 164

It would be interesting to learn the name of the anonymous Swiss private collection in which this lekythos once resided. (And note that this information is derived not from Royal-Athena Galleries but from the present vendor.)

We also note the appearance of the Kluge collection.
