I cannot find information about this anywhere. Maybe someone here can help. How should I go about formatting sign names? Quotes, italics, nothing at all? For example: A sign above the door read, "Restroom." She sat down at his desk, at the corner of which a plaque showed his name: Dr. Adams. He stopped at a locked gate barred by a sign reading Trespassers Will Be Prosecuted. Is there a specific rule for this, or is it one of those gray areas, in which you choose one method (quotes, italics, or nothing at all) and stick with it?
