As one of the first comprehensive histories of newspaper comic strips, this coffee table book does a very good job of highlighting the important strips, and strips that have fallen into obscurity (there are a number that I had never heard of). Yes, there are some omissions, and the strips that are included often are token samples. Thankfully, in the almost half century since this book was written, many compilations have been published by the likes of Fantagraphics, IDW, and Sunday Press. But this is a good place to begin. The reproductions are excellent, although there are some Sunday strips that are only in black-and-white. The editors' commentary is fairly sparse, leaving room for more artwork, but perhaps leaving out important historical data in the process. There is a nice annotated index at the end of the book which supplements some of this information, but is still a bit short on details. Although this book measures a hefty 10" x 14", some of the early strips are nevertheless shrunken from their original tabloid size, making some of the captions and dialogue balloons hard to read. One of the clearest take-aways from this book is how strips evolved--from meticulously drawn and text heavy when newspaper pages were large to today's much more simplified renderings as comic pages got smaller and smaller.
This book presents the strips in their original forms. Thus, there is racism, violence (including domestic violence), and a general lack of diversity. Some of the racism is quite bad, but overall I think most readers will be able to put the stories into the historical context of their times. There is also a sequence in the Wash Tubbs selections that graphically depicts the killing and rendering of a whale, something you would never see today.
