Charles Fréger is a French photographer who has done some interesting photo series. I recently bought his photo book "Wilder Mann - The Image of the Savage" and cannot believe that I have been unaware that there are so many cultural traditions of this kind still going on all over Europe. Some of the costumes are funny, some are creepy, some nightmarish, but all are fascinating. The book includes further information on the costumes and rituals, including where they take place and when.
This outfit here is my favourite. It looks like the outcome of a romance between a Yeti and Marge Simpson.
