My head always turns when I see a photography book sitting face out on a shelf. It’s probably a throwback from when I was little and only liked books with pictures. But now I can appreciate “picture books” with more grown-up themes. The latest one I’ve come across is a re-issue of The Americans by Robert Frank with black-and-white pictures from the 1950s. The faces of the people and the moments Frank captured are sometimes comical, sometimes haunting. Most of all they give you a picture of who we Americans were not so long ago.
