Each of these awesome sculptures is made of marble. Look closely and you still might not believe it. Your eyes tell you that Mona Lisa and skull are clearly made of styrofoam, but they were both carefully carved from solid marble by Italian artist Fabio Viale.

"Viale does some incredible work to modernize this “old-fashioned” medium, like re-creating Greek Korus torsos and hands covered in tattoos. He is able to transform this heavy, bulky material into creations that seem light and airy, like old beat up tires popcorn or crumpled paper bags."

He even created a roll of marble toilet paper! It’s beautiful, playful, and incredibly detailed work.
