This beautiful US map is a historical gem, capturing a snapshot of the country as the Interstate system expanded at a torrid pace. This February 1968 US map featured beautiful cartography--combining many layers of information into an integrated whole that is as artistic as it is informative. The map is a perfect companion to the US map of 1961, which showed the beginnings of the Freeway system that soon became the Interstate Highway system. A great historical reference, and a perfect addtion to any map collection.
