Fabio Isman has published an article noting how items identified from the Medici, Becchina and Symes photographic archives are surfacing in the New York Christie's auction this June ("La Grande Razzia è ancora tra noi, e Christie’s lo sa", Arte Magazine, May 2013). He includes a number of photographs from these dossiers, and gives credit to Christos Tsirogiannis for the identifications.
He poses the question, what will Christie's do?
We know what Christie's should do if they are serious about due diligence. A member of their antiquities department should contact the cultural attache at the Italian Embassy.
Is that what will happen?
