Architecturally detailed map showing the National Mall and adjacent areas, including the US Capitol building, the White House, the Lincoln Memorial, and the Jefferson Memorial. The "axonometric" technique gives a primitive illusion of three dimensions, for it does not use true perspective, yet, the sides of buildings, trees, and elevated highways are drawn in a foreshortened manner. You can count the rows of windows on each floor of important buildings, and these are readily recognizable (see sample at right.) Streets, bodies of water, and some important structures are labeled.
