Happy Sunday, and welcome to map week! Starting now, going through the rest of the week, we’re posting a map each day, so get pumped. GoDCers love maps! And this is a great one to start with.

Here’s a map covering Observatory Circle, Woodley Park and some of Glover Park from back in 1913. Pretty cool stuff. You’ll notice a few different things, like Calvert St. wasn’t there, Whitehaven St. was W St., and a few more things.
