Wendy McNaughton is an artist whose work is being seen increasingly all over mainstream media, and good for her, though I first became familiar with her through the site Brain Pickings and The Toast, as well as I Love Charts, the tumblr. This is a beautiful, random portrait of the people & parts of San Francisco, along with some words. It's very stream of consciousness, and the portraits of people, places and things are incredibly humane, from the grand things to the mundane. It's a book full of love, and beautiful drawings to boot.
You won't come away with a new trove of facts about San Francisco, but you will have a better feel for its heart.
