Here's a nice old advertisement for the new development in the western half of Washington called the "Palisades of the Potomac." The advertisement was created by the Palisades of the Potomac Land Improvement Company in June of 1890.
I came across this while looking through the Library of Congress
' American Memory
pages (which are kind of ugly and hard to navigate). There are some really interesting old maps of D.C. in there.
The Palisades is a quiet and beautiful neighborhood at the very edge of the District diamond. It's home to some of the nicest detached houses in the city, some with great views over the Potomac.
