Answer:
Nazi Looted Art
Explanation:
Dormant bank accounts, transfers of gold, and unclaimed insurance policies, all taken by the Nazis and hidden primarily in Swiss bank accounts during World War II, are now the subject of economic and financial research. Museums and galleries are researching the provenance of paintings, decorative arts, and sculpture in their collections in order to confirm that none of the pieces were looted during World War II. https://www.archives.gov/publications/prologue/2002/summer/nazi-looted-art-1.html
