No Writing or Marking Allowed Sign - Visual Guide & Usage #3493533 (License: Personal Use)

The image displays a standard prohibition sign: a red circular border with a white background and a black pictogram of a stylized person writing on a rectangular board (e.g., whiteboard or chalkboard). The red circle with diagonal slash (implied by the prohibition convention) signals that the depicted action is forbidden. This symbol is commonly used in educational, office, or public settings to prevent unauthorized writing or defacement.

This sign is typically placed near whiteboards, glass partitions, or display surfaces to discourage vandalism or unauthorized use. It matches user intent for understanding signage compliance, facility management, or safety communication.
