This is a reblog of a 30 November 2013 post at Infernal Wonders, with an image originally from the (somewhat to my surprise) still-extant tumblr Suspect Unknown. It appears to be a promotion poster for the 1986 horror movie Bijo no harawata (Entrails of a Beautiful Woman).
Looks like someone’s about to mutate…
Huh. That is pretty insane.
