Cement Nut Skull
This Cement Nut Skull is one from the archives of the superb Skull A Day. I’m not sure how much this cement skull weighs but what I can tell you, it ain’t no paperweight.
As you can tell from the image, the surface of the cement skull has been meticulously embedded with metal nuts.
R Hayes, an artist residing in Minnesota, was the creator of this colossal skull.
