Thanks Sybarite and Stewart, for solving a mystery of long standing!
Look at this Wiki entry:
Andrei Chikatilo - Wikipedia, the free encyclopedia
I had never heard of Chikatilo, but I remember a curious photo, cut out of the
Baltic Times or some such newpaper, and which had been pinned up on the wall of the toilet of friends of mine - and stayed there for at least a decade. I never understood whether the photo was a joke or real when I read about cannibalism. There was only the caption, no further text. Now, the mystery has finally been solved by your discussion here.
I imagine that the photo was put up during Chikatilo's second imprisonment. I'm not into this sicko stuff myself. I'd rather read a Rankin or a Conan Doyle, not wallow in all the stuff you can read in gory detail in the Wiki article.
