Requires signage be placed alongside art and artifacts stolen during the transatlantic slave period and the domestic slave trade period indicating such material was stolen

The requirement now applies only to identifiable works of art and artifacts created before 1900, rather than all cultural materials regardless of creation date.

The definition of eligible items was expanded to include works created using metal materials used in the exchange for enslaved human captives.

The geographic scope was restricted to items that changed hands in Africa or the United States, removing references to other locations.

The historical period covered was updated to explicitly include the Reconstruction era (1865-1877) alongside the transatlantic and domestic slave trade periods.

The signage requirement was updated to acknowledge that the items were created using materials exchanged for enslaved captives, rather than just stating they were stolen.
