Members of the Koatlacker devil's association (Koatlacker Tuifl) dressed as demonic creatures take part in a Krampus procession on December 4, 2011 in Prad near Merano, Italy. In the tradition, which involves elaborate masks, some of which are centuries old, the devils accompany St. Nicholas when he visits little children to determine who has been good or bad, and the tradition is still practiced in Austria, southern Germany and the South Tyrol region of northern Italy.
