This poor tree torture victim at the Wax Museum at Fisherman's Wharf hangs upside down at the museum's chamber of horrors section. Although this is one of the less gory scenes, it is still fairly disturbing based on the body language of the figure. The victim screams pain without saying a word.
This is how the figure looks as you pass by the dark chamber. I assume this is the tree torture scene, as this is the only one that seems to match that description from the museum's guide.
