It's probably not a good thing to have the first image of the book look like it was grabbed from the Internet. It's not just that, many of the pictures are slightly pixelated.
Fortunately, the book features a good variety of work, and from all over the world, judging from the number of languages I cannot recognise.
This 308-page book covers public, commercial and exhibition wayfinding graphics. There are lots of interesting ways as well as conventional examples of displaying graphics. I'm not sure all of them work for me though. The selection of work is quite good so it's a helpful reference.
