Argentina's Holocaust Museum has taken custody of a huge trove of National Socialist artefacts seized in a house raid in the capital, Buenos Aires, two years ago.
A bust of Adolf Hitler is among the 70 items investigators had found.
Another was a head-measuring device - a relic of pseudoscience used to measure racial purity.
The items were found hidden behind a false wall at the home of a collector in 2017. He said they were replicas but experts say they are authentic.
It is legal to own National Socialist objects in Argentina, as long as they are not used to "incite hatred".
But the owner has been charged with "owning pieces of illegal origin" because they are suspected of having been smuggled into Argentina.
After the regime fell in 1945, some of the highest-ranking National Socialist officials fled to Argentina including the famous Josef Mengele and Adolf Eichmann.
The Holocaust Museum in Buenos Aires says the hoard of items found in 2017 will be added to its exhibits.
The objects encouraged "hate, death and destruction," says Director Marcelo Mindlin, but will go on display "in the service of transmitting democratic values, education and the fight for memory so tragedies like the Holocaust are not repeated".
