I only took this picture a couple of weeks ago and it has been buffed over at least twice since then. It is by the irrepressible Laic217 who never tires of creating these wonderful skulls and skeletons in various guises.
This skull is donning a gas mask, or is it a sophisticated protection mask from the fumes of spray paint? I guess perhaps the latter and the yellow patterns are the paint fumes. It works either way really. The detail in the eye sockets of the skull is awesome and the bucket hat with the smiley so full of character. Laic217 has smashed it with this one.
