Wow! Check out this KrampusLauf on YouTube! Awesome! Look at those costumes and HOW MANY there are!!! Why don't we have this here!? Thank you, Melanie, for the link!
I found this most unusual Krampus in a book, "The World Encyclopedia of Christmas" by Gerry Bowler. He's almost a pet here, not as humanoid as other images. Still, he's definitely a demon, definitely creepy and definitely dangerous! Look at that tongue!
(Sorry for the not-so-great scan, I didn't want to snap the book's spine.)
