The USGS publishes two outline maps of the world. Both are printed in two colors and use the Van der Grinten projection centered on the Americas. The outline format makes them useful as base maps on which you can compile and display special information. This 48"x33.5" map shows the boundaries and names of nations. It shows their capitals and major cities. Map scale is 1:40,000,000 (1 inch equals about 631 miles).
