This detail of a photograph in a Philadelphia yearbook, 1968, has clearly captured a being from the Otherworld.  We've identified this creature as the long-nosed seducer demon Zanni (of Harlequin mask fame).

We sensed something disquieting about this photo and analyzed it with our custom Uncanny Detector app.  Note the enlargement of the face on the figure at the right.  There is a long snout protruding from a dark face with shaggy blond bangs (or some sort of jagged hood?), the right eye (on our left) gleaming.  But also -- protruding from the side of the figure's head (on our left) there is a second face in profile, looking downward, with a very sharp nose and the hint of a smile.  Do you see these details like our app did?  Blurred as it may be, this is clearly an entity from the Otherworld.
