The only thing unique about this map compared to the other US wall maps we sell are the 21 inset maps across the bottom which show details of urban areas.  Typically, at the scale of a US wall map, there are too many suburban cities around a major city to show them all—the print would be too crowded or tiny if a mapmaker tried to do that.  But by using larger scale insets, many more cities can be shown.  For example, on this map there are over three times as many cities marked on the inset map of the San Francisco Bay Area as there are on the main map.  Since most of the population of the United States lives in urban areas, this map is more likely to show the city where you and your friends live (or your potential customers) than are the other ones.
