I'm being a little picky about the 4-stars, this is an elegant and gorgeous map. I would have liked either: some cities being clearly labeled, as it is you can't really read any of the map underneath the geologic colors, or, some rivers being overly emphasized color-wise and clearly labeled. I feel like I'm going to make a large place mat out of it instead of put in in a frame on the wall. I want to study it and not just enjoy the beauty from afar.
Still highly recommended! Worth it easily, I've never seen maps like these.
