Michael Sherwood and his son Kyle have spent years developing a special process that preserves a person's skin and the tattoos on it after they die.

They say they came up with the idea over some drinks with friends. One friend had recently lost his father and told the pair he wanted his father's tattoo preserved.

They laughed it off at first, but the friend's persistence got them thinking.

"With the art in tattoos and how much they mean to people, why not keep them after they die?" Kyle said. "People put ashes in urns on mantles and visit stones with their loved one's names on them. Why not keep their tattoos as a memorial?"
