Dr. Marsiletti owns a 15th/16th-century ivory saltcellar made in West Africa for export to Europe. He received permission for an international sale from the Italian government and put it up for auction, but on the day of the sale the Italian government rescinded their permission. The Marsiletti family contacted me for detailed information that would allow them to counter the government's claims regarding the importance of this particular work. They are seeking authority to overturn the decision made by the government.
