I almost want to visit Scotland just to see this postbox. It really does look like it belongs in Middle-earth, just as suggested by the poster of the photos, Roman Sock. Of course, the postal service in Middle-earth is a bit of an anachronism, as Shippey points out. Along with tobacco, tomatoes and so forth. But who really minds? The hobbits, after all, are one of Middle-earth's wonderful quirks.
