Can't believe I managed to miss seeing this yesterday! I was back to pick up a prescription and thanks to a photo I'd seen online I realised that  I only had to walk a bit further up the road (as in about 20 steps or so!) and I saw it. I'd looked at the wall opposite and didn't register to look at that one. The photo I saw also had a seagull surveying as only they can do on the same post.
