The meaning of 1970 for the acquisition of archaeological objects
Many museum and professional associations, particularly in the United States, have adopted a 1970 standard for the acquisition of archaeological materials–that is, in recognition of the 1970 UNESCO Convention on the Means of Prohibiting and Preventing the Illicit Import, Export and Transfer of Ownership of Cultural Property, archaeological objects should be documented has outside of their country of origin before 1970 or have been exported legally after 1970. This article explores the extent to which this standard has been adopted, its influence on restitutions and claims for restitution of archaeological objects, and the policies that this standard attempts to promote.
