Sign in the window of the Martin Luther King Jr. Memorial Library:

“Washington, D.C., one of the world’s great cities, deserves a world-class central library. We looking at the possibility of a new central library on the site of the existing convention center.”

(Note: In neat handwriting, with a black marker, someone has put a caret and the word “are” between “We” and “looking.”) —Annys Shin
