Creepy Halloween Photos From Over 100 Years Ago

Here are 5 photos from artist/musician Ossian Brown's 2010 book Haunted Air -- a collection of Halloween photos dating back between 1875 and 1955. Some of these photos are over 100 years old, and like a fine wine the emotional triggers of these moments in time have only become more subtle and complex with age. I get the weirdest vibe looking at these. The fact that I can't see most of their eyes doesn't help. What creeps you out the most in these photos?
