In the battle between the San Francisco picture books between this book and the other similarly named book I just looked at, this one wins.
It’s bigger in size, it’s thicker, and it’s got higher quality paper and photography. It also relies on locals for the essays within, including Herb Caen, Herbert Gold, and others, so you get a better sense of place and the people of San Francisco. The essays are essays, too, instead of just text blocks around which to group the images.
So if you have to choose one or the other, this is the one to go with. As probably demonstrated by the fact that it has gone into a third edition.
