Those blue and white Parisian street signs evoke much delight. To the Francophile, moi!, these utilitarian signposts symbolize such bons souvenirs de France. I'm not the only one. They have a cult following, it appears. A bit of online research yields a dizzying amount of trade surrounding the ubiquitous bleu et blanc. Companies like Emaillerie Normande will customize them with any message you want. Or you could choose from their own selection: LAPIN LUNATIQUE or HAMSTER MALICIEUX or ENFANT TERRIBLE. Drôle.
