Despite every best effort, many museums have made acquisition mistakes in the past and unwittingly accessioned works of art that were stolen from storerooms or plundered from archaeological sites. No museum should deaccession an object without having a justifiable reason for doing so. If, however, an investigation turns up looted antiquities in a museum collection (for example, if photographs show an object shortly after it was illicitly removed from the ground, or if its provenance documentation was demonstrably forged), then a museum has an obligation to redress the break in the chain of that object’s ownership in some way. Usually such a resolution is achieved through a financial settlement with, or physical return to, the country of modern discovery. Museums hold their collections as public trusts, and no museum should wish knowingly to retain stolen property on behalf of the public.
Regardless of how a museum shares information about provenance, the most important goal is to be as forthcoming and accurate as possible. To that end, documenting an object’s provenance may involve not just tracing its history of ownership (what do we know?), but also recording the sources of that information (how do we know it?), and noting the differences between verified and unverified data. Information about provenance can come from verbal statements, circumstantial evidence, or attestations provided by a seller or donor that have not been (and often cannot be) corroborated. Museum records should reflect these uncertainties and any vague or hypothetical statements.
When this worked fine, he could hardly contain his joy, and when he couldn't hear any activity noise outside, at last, he sighed in relief. This didn't last long tho. This damn driver started blasting some of the worst pop songs ever made on the radio... and singing along. Real loud. He could only suffer in silence as music that was terrible even by teenage girls standards drilled into his ears. As for the singing, he was so far off.
