Maurizio Cattelan may have, as he claims, retired from making art, but his cunning sense of the mischievous and macabre hasn't stopped haunting the public. Consider the new book Toilet Paper (Freedman/Damiani). a collection of surreal, unsettling images (like the one above) Cattelan and and photographer Pierpaolo Ferrari created for their two-year-old magazine of the same name. Paired with similarly peculiar texts (among them Jonathan Swift's devilish satire "A Modest Proposal," which suggested that the Irish should eat their homeless children), the volume reads as one long, extraordinarily vivid dream.
