President Obama did a wonderful thing for historians by agreeing to allow a 3D image of his head to be created. My question is, is the model to scale? Is it the exact same size as President’s Obama’s real head?

Obviously, you can’t walk up to a sitting president and put a tape measure around his head, but they might let people put a tape measure around the cranium of President Obama’s likeness. They might even let a devise like this be used, for accurate measures of head width, head length, and head height, allowing historians to measure cranial capacity.
