This is but one of several heads mounted along the walls of my grandfather’s house. They used to scare the hell out of me when I was younger.
It did not help that my grandfather would tell a story of how the house was built by a father and son and that the heads, mounted along the wall (which appear to either be laughing or screaming, depending on my mood), are supposedly meant to look like the father, murdered by his son.
I love my grandfather, although the story he told was probably completely false. The house was most likely built by sadistic elves who liked to give small children horrible dreams.
