The No Photography 8315 Sign has a symbol on the top and the written words on the bottom. It is intended to advise people that they are not permitted to take photographs within a specific area, whatever the reason might be. The sign is photoluminescent and will therefore glow in the dark.
People may not be aware that they are restricted in taking photographs, unless you display a sigh that will advise them otherwise.
Fixing requires anything as simple as sticky pads, 'No-nails' type adhesive or double-sided tape.
