No photography

I couldn't resist this blip.

Where did it find me ?

Was it in a top secret government research establishment ?
Was it on the headquarters of MI5 ?
Was it in an airport ?
Was it by an army training camp ?
Was it at the entrance of a fashion house ?
Was it in a place of natural beauty and interest where they might lose a fortune in selling souvenirs ?
Was it at the LanXess Arena during a rock concert ?

No

This sign was on the wall of WH Smith at The Fort Shopping Centre, Birmingham (where they sell cameras)
