Among them were a bust of Hitler, medals, a sculpture of a swastika-emblazoned eagle, a sinister device to measure the size of heads, and a magnifying glass that was used by Hitler.

Argentina’s security minister, Patricia Bullrich, confirmed that the objects were “originals”.

She said that some pieces, including the elegantly encased magnifying glass, came with photographs showing Hitler using them.

“This is a way to commercialize them, showing that they were used by the horror, by the Führer. There are photos of him with the objects.”
