Professor Susumu Kato of the book "Pigment of the Imagination" actually collects tattooed human skin. It is described as a "soggy bundle of technicolour tripe", not hardened papyrus or construction paper. Note the lack of ashes or dark ash stains on the "pelvis bone ashtray". The alleged human pelvis ashtray conveniently disappeared after the presentation, along with many other props. Ilse Koch, the wife of Buchewald's Commandant Karl Koch, was blamed for these false atrocities. Konrad Morgen of the SS led an 8-month corruption investigation against Ilse and Karl. Lying allegations by prisoners were investigated and found to be untrue. For executing prisoners, Karl Koch was executed by the SS a week before Buchenwald was liberated. Why would "Nazis" execute one of their own for executing camp inmates, when the narrative was "their intention was mass execution of prisoners"? Ilse Koch was acquitted, for lack of evidence. Even so, she was later given the nickname "bitch of Buchenwald", which the same liars also claimed she wore "human skin gloves", had "human skin soap" made, and fashioned "human skin book covers". Inmates never referred to her by this nickname. It was applied later.
