It is awkward to enter a meeting room and not be sure it is your organization. Hotels routinely label their lecterns with their name or logo so it will be prominently displayed in news photos.
Scientific and social groups need to practice the principle of identification. It is a useful habit to display the name or logo of the organization in every meeting room, usually in the front of the room on a lectern or easel, or on the wall. It provides an identity and contributes to organizational pride.
