Pigs tattooed with the Louis Vuitton logo have been banned from the Shanghai Contemporary Art Fair. Wim Delvoye, a 43-year-old Belgian conceptual artist, tattooed the pigs when they were babies and tracked the tattoos (he calls them "canvases") as they grew. Animal-rights activists complained, and the fair officials decided to remove the pigs. The artist says the animals are treated humanely and given sedatives before getting tattooed. [Telegraph]
