But some disputed cultural property could have surfaced before that crucial date. Take for example these three examples:
- The Lydian Hoard returned to Turkey from the Metropolitan Museum of Art in New York (see "Bonham's, Lydian Silver and a Code of Ethics" a related piece offered by Bonham's in London in 2007)
- The Keros Haul from the Cycladic islands in Greece
- The monumental Roman bronze portrait statues from Bubon in Turkey
Is the 1970 merely a helpful and convenient marker? Is it hard for a museum (or a private collector) acquiring antiquities since 1970 to say that they were unaware of the issues?
And where do national laws on antiquities fit into all of this?
And what about objects that were acquired before the creation of modern nation states?
