I note a previous reviewer commented that this would be a good book 'for teaching kids'. He misses the true value of this book - it teaches adults! Cartoons are useful in not only teaching history, but also the social mores and attitudes of the society which produced them. Books like Benson's '20th century' have great and intrinsic value in history, politics, international relations, sociology, language and literature etc. So much more than simply 'teaching kids' history. This book is to be commended to any student of any of these disciplines as a fine example of the analysis of the cartoonists' art.
