Jason Felch has reminded us of the impact of toxic antiquities on museums. This time he has looked at the collection of Greek pots at Haverford College. The collection was derived from George Allen who worked for Hecht's Hesperia Art in Philadelphia. Interestingly one of the pieces looks like it comes from a known looted temple in Turkey (but we need to wait for Felch's publication).
This story will be making very uncomfortable reading for other museums that acquired objects from Hesperia Art - and not just in North America.
