Keeping your eyes open will pay dividends because people do the daftest things. So I screeched to a halt when I saw this old-fashioned signpost beautifully adorned with a period lampshade. I wanted to create an appropriately retro image so I gave it a black and white treatment. I wonder if it was the bulb-shaped moulding at the top of the signpost that inspired the anonymous prankster. Perhaps they'll add a switch next time: I'll keep my eyes open.
