Something different, just ran into this and felt like I wanted to share it. ‘Olga, the Headless Girl’ was a show of illusion brought from Hamburg to the United States by a man who called himself “Dr. Heineman”.
The show was also presented at the Universal Exposition in New York in 1939, and has since become a very popular sideshow show, still in vogue in the ’70s and’ 80s of the last century. Exploiting the taste for the macabre, the show, despite the awareness of illusion, had to be (at least in the pre-war decades) rather terrifying: a woman, beheaded for some reason, was kept alive thanks to the tubes that, coming out of the throat went to a device that had to provide the necessary nourishment.
