In October 2011, Christie's South Kensington is due to auction some 40 lots formerly owned by the Belgian collection Jacques Werner. Several of them are Italian in origin (Canosan terracottas, Etruscan bucchero, Etruscan terracottas, Apulian pots). The earliest acquisition seems to have been made in 1979.
I notice that 20 pieces (not lots) were acquired from the Galerie Archaeologia in Brussels between 1984 and 1992. Where did that gallery obtain its antiquities?
