But these were not the only pieces on display:
Police also showed off some of the 251 artifacts, worth a total of some €2 million, discovered as part of another investigation, dubbed Operation Phoenix, into looted antiquities found in Switzerland.
The goods were handed over to Italian authorities by two Lebanese brothers who operated a Geneva antiquities gallery. Police said they hoped that such a gesture would be repeated by anyone who had illicit antiquities in their possession.
It does not say when these antiquities were seized or provide the names of the two Lebanese brothers in Geneva. (See also the report by Adam L. Freeman, "Swiss Gallery Surrenders EU2 Million in Antiquities to Italy", in Bloomberg, May 19, 2009.)
I can only find mention of a Swiss-Italian raid on a Geneva warehouse back in 2001 that included less than 100 terracotta items (mostly pots) reportedly found in Italy.
