BUENOS AIRES (Reuters) -Dozens of boxes of Nazi material confiscated by Argentinean authorities during World War II were recently rediscovered in the Supreme Court's basement, the court said on Sunday. The 83 boxes were sent by the Germany embassy in Tokyo to Argentina in June 1941 aboard the Japanese steamship "Nan-a-Maru," according to the history that the court was able to piece together, it said in a statement. At the time, the large shipment drew the attention of authorities, who feared its contents could affect Argentina's neutrality in the war.
