John MDC is a "bone"ified bad ass skull artist. Almost everything he creates is of the skull. He's been featured on our site multiple times (here, here, here, and here) and that should stand as a testament to the multitude of skulls he has to submit.
John's site is teeming with skull art. Prints, jewelry, shirts, etc. I don't know if I've ever seen so much skull art produced by one person, aside from our own Skull Master of course. Thanks again for the great submissions, John!
