It belongs in a museum

This is a contentious issue. An auction house in Queensland, Australia, is selling Nazi memorabilia, including a signed photograph of German dictator, Adolf Hitler, a propaganda children's book, and SS artifacts. A company representative sought to justify the auction as a legitimate business activity, but there is the very real danger that these items may fall into the hands of neo-Nazis, as is the opinion of a Jewish community group spokesperson quoted in the article. 

Rather than sell them to make money, arguably these items should be donated to Holocaust museum. This will allow them to be displayed to inform and educate society about recent history, and not be used as a conversation piece for a private collector, or for more nefarious purposes.
