Here’s an old advertisement that we found in The Washington Times from Saturday, June 4th, 1910. It shows a row of homes on Clifton St. in Columbia Heights, recently finished, and for sale at $7,750.

Here’s the Street View on Google today.
According to Zillow, 1211 Clifton St. NW sold for $822k earlier this year. It looks like the house on the corner may have been divided into units at some point. It’s a rental now.

I would like to have seen the interior pics from 1910.
