"Ichabod" Plague Doctor mask by Tom Banwell
I've always found plague masks fascinating. On one hand, they have a grounding in actual history; one the other hand, they look like something out of a fantasy novel. They were worn by physicians attending plague victims, which ought to make them a sign of peaceful intentions, and yet, there is something singularly terrifying about the faceless, avian aspect of a person wearing one.
Few people on the net do plague masks as well as leather worker Tom Banwell. Here's an example of one he did last year that I think represents his best work. If you like it, make sure you sure on over to his blog to check out the rest of his work.
