This 19th century building on the corner of JFK Street and Brattle Street in Harvard Square   is reminiscent of the Flatiron building in the city, albeit on a much smaller scale. One third-floor corner office has a supposed law firm’s name etched into the window “Dewey, Cheetham & Howe.” The sign is a joke asking the question we presume lawyers ask themselves, that is, “Do we cheat them and how?” This sketch is from a picture I took.
