Please Knock Sign - Polite Door Notification for Homes and Offices #3506177 (License: Personal Use)

This minimalist white rectangular sign features bold, centered serif typography reading “Please Knock”, mounted on a thin black border and suspended by two strings from a small metallic nail or hook. The high-contrast black-on-white design ensures readability from a distance, and its clean aesthetic suits both residential and professional environments. It conveys respect for privacy without appearing unwelcoming.

Commonly used on front doors, office entrances, or shared living spaces to politely request visitors announce their presence before entering. Matches user intent for home decor, etiquette signage, or workplace boundary-setting solutions.
