1907 Map of Kalorama, Subdivided and Unbuilt
This is a really interesting look at a neighborhood, where today, the total value of the properties hovers probably somewhere near $200 million.
This map is from 1907 and shows the area completely subdivided, with almost no buildings. Totally fascinating.
