“Dear PoP,

I wanted to let you know about some new artwork in the display cases outside the Convention Center at Mt. Vernon Square. The cases are under the Convention Center bridge, which I pass everyday walking from the metro to work. They’ve been empty forever, it’s great to seem them put to use, and there are some really interesting pieces. I especially like the DC street map done in yarn and pins. If you’re down that way you should check it out.”
