Is there any chance, that you'd know where these Buchenwal exhibition items are today? President Eisenhower ordered that exhibition to take place and audience was the citizens from city of Weimar. I'm mostly interested to know where I could see these human skin lampshades, shrunken heads where hair still grows and ashtray made from human pelvis.
I emailed Buchenwald museum years ago and they didn't know. They provided me a link from their website, which states that human skin lampshade is fake: https://www.buchenwald.de/en/geschichte/themen/dossiers/menschliche-ueberreste/kleiner-lampenschirm
Your assumptions are worse than your arguments lol
