Every Monday I will show off my collection of maps that I have been collecting over the years these range from some the oldest maps with some great history connected to them. To the cheapest throwaway maps that are given out in every major city in the world. I don't believe in keeping it in perfect condition so still have marks on them too which you can extract a story from just like your own treasure map.
The transit map of the world by Mark Ovenden is a beautiful source of information design examples of maps. While the maps are very informative with a wide range of maps within the book some of the images do fall down in quality I don't know if this is a printing production problem or the quality of the original images used within the raw source material.
