Musée d'Orsay finds bottom-toning belt firm to sponsor nude male art show Business and art are uneasy bedfellows, so hats off to the Musée d'Orsay, which has found a fitting sponsor for Masculine/Masculin, a survey of "the nude man in art, from 1800 to the present day." The show, featuring 200 portraits of buff men, by artists from Rodin to LaChapelle, is supported by Slendertone, supplier of "abs belts and bottom-toning kits" to bodily insecure men the world over.
