The authentic vintage French enamel sign has the bold warning text "OUVERTURE INTERDITE" (meaning "Opening forbidden" or "No entry") in striking black lettering against a vibrant yellow background, enclosed within a contrasting black border. This long narrow metal sign captures industrial and utility styling, perfect for adding a touch of authentic French character to an interior space. The condition is excellent, with minor signs of age and wear as shown in the photos and revolving video. It measures 40 cm by 8 cm and weighs 350g.
