This pictorial map depicts the history of the United States, with history seeming to be defined as colonial activity -- or even more broadly, white history (although it does record the historical locations of several Native American tribes). It records historical events such as battles and colonial discoveries; historical locations such as white American settlements and the place where the sod breaking plod was invented. The illustrations are largely confined to state borders, with the exception of rivers and migration trails or army marches. The bottom of the map contains insets with expanded illustration and context for a number of regions and events, such as "The Frontier" and "The Declaration of Independence". The map also extends beyond the borders of the United States and points out the colonial events on several colonial islands, in Mexico, and Canada, as well as routes that colonial explorers followed.
Follow the words wrapping around the border and you'll see a quote from the Gettysburg Address.
