I made a World Political Map that brings together several products that I have helped develop through the years. They include Natural Earth vector data, a manual shaded relief of the world, and the Natural Earth, Natural Earth 2, and Patterson projections.
The three versions of the map are available as layered Adobe Illustrator files that you can use “as is” or modify to create new maps. They are in the public domain. The version in the Natural Earth projection has MAPublisher georeferencing and I hope to georeference the other two projections later this year.
If you see any errors or inconsistencies, please send me a private email.
