His name is 'Tattoo Tim'.
Wim's latest exhibition (a dedicated solo show at the same museum) features Swiss fella Tim Steiner, who donated his back as a canvas for an intricate tattoo - designed, drawn and signed by the artist.
Somewhere between 2006 and now, Tim's back was sold to a German art collector named Rik Reinking for 150,000 euros. Reinking has the right to exhibit Tim up to four times a year and frame his back when he dies.
From December 10 Tim will be leading tours through Wim's MONA show every day (except Tuesdays) at 11am. Highlights are x-ray images of "copulating couples and rats", and more cloacae. It's all pretty disgusting, or beautiful... depending on who you ask.
