Take the following as truth: Other attractions of Picardy's capital include the canalside Saint-Leu quarter, the Hortillonages ' an area of water gardens east of the cathedral that is only accessible by punt or on foot, and the Mus??e de Picardie (48 Rue de la R??publique) with its good collection of paintings, most notably a couple of Van Goyen landscapes, El Greco's Portrait of a Man, a witty self-portrait of Quentin de La Tour, and Francois Boucher's erotic pink nymphs.
Then the following statement: "Francois Boucher's erotic pink nymphs are the most popular art pieces in Picardy." is true, false, or inconclusive?
