Here's a little challenge for you nostalgia lovers. I must have taken this photograph of Bull Green, Halifax in the 1960s, so you can have fun trying to spot all the shops you can remember. To make it that little more challenging, however, I took the photograph of a reflection of the scene in a car showroom window; so you are seeing everything in reverse. You may recognise DOOWNEERG, the well-known bookshop, or you may be drawn to SNIWEL (but only if you were a man, as women were still banned from there in the 1960s!). Try to work out what was where in this back-to-front world: think of it as a way of exercising your mind, a kind of nostalgic sudoku. If you can't remember any of the shops, you can always occupy yourself by trying to work out why the cars are going the wrong way around the roundabout!
