This is the Upside Down Map. There is no official explanation of/for this map other than it is a map of the world drawn from a different perspective. Since we are so used to seeing maps from one perspective, when that perspective is altered, it makes it harder to comprehend. Despite the fact that all the "shapes" of the land masses are the same, it took some time to find the United States because it seemed to be oriented incorrectly (in my mind.)
