The Original Two-Face!
We're not talking Harvey Dent here but rather a few examples of...
...上下絵 (Joge-e) or two-way pictures which are a type of woodblock print that can be viewed either rightside-up or upside-down. Large numbers of these playful prints were produced for mass consumption in the 19th century, and they commonly featured bizarre faces of deities, monsters or historical figures. Only a few examples of original joge-e survive today. So courtesy of Pink Tentacle, here are a few:
Created by Yoshitora, 1862. Left column (top to bottom): 1. Tadafumi (Gedo, an evil person), 2. Hunter (Frog), 3. Small tengu (Big tengu), 4. Bad guy (Bad guy). Center: 5. Two-horned demon (One-horned demon), 6. Kasane, possessed female character in famous Kabuki play (Ugly man), 7. Daruma (Daruma). Right: 8. Foreigner (Ainu), 9. Nio guardian (A-un guardian).

If you are really interested in this, you could always buy your own via Amazon.
What all this brings to mind is Mad Magazines' Al Jaffee who created the fold-in art covers that made wry political statements that even I could understand. Click on Al Jaffee to behold some of them for yourself. Good stuff.
I came across this picture today on Yahoo Japan and it features a politician who flip-flops occasionally, so I think it's worthy of mention here. (Of course, he's not as two-faced as his opponent, but I suppose he's the lesser of two evils.)
Not the most Halloweenish post I know, but some of the joge-e are kind of creepy!
