There's a local artist named R. Hayes in the land of 10,000 lakes(Minnesota) who invested a fair amount of time and effort to prove how nuts he is about skulls.
If you're nuts about skulls, and I know you are, then you have to admit that this skull is worth it's weight in concrete. I'm sure it took a lot of time to create the smooth finish. The look is great, very machine like, yet very scuplted and natural. Not to mention it's probably pretty hefty as well. Thanks for the heavy metal(and concrete) submission!
