A specialization of HardcopyInformationBearingObject. Each instance of SignTheDisplay is a physical object typically placed where Persons can see it so that they can obtain (generally propositional) information from it. Signs are typically used to identify objects (e.g., street signs, name tags, species labels at zoos), to advertise goods (e.g., billboards, neon signs, posters for garage sales), and to warn of hazards (e.g., signs for road hazards or road construction, printed tape marking off a police line). SignTheDisplay differs from SymbolicObject in displaying specific information rather than symbolizing another thing, though the two collections are obviously not disjoint. See also signifiesTo, signifies.
