Ceci n'est pas un panneau d'affichage

City officials in Des Moines have cited a local middle school for a mural depicting children learning and playing. Since the mural includes the school's name, the city says, it amounts to an illegal outdoor sign. By contrast, a controversial painting of a nude angel on another Des Moines building does not run afoul of zoning rules because it is art, not advertising. School officials are thinking about painting over the words on the mural.
