Most of the old picture postcards shown depict historical events, local scenes, people, animals, different provinces and cities during the period, old US Army camps and forts, ships and boats, old buildings that do not even exist anymore, manners, customs and traditions, costumes, local transportation and practically all phases of life prevalent in the Philippines during the period of the US colonization of the islands.

What's so interesting is that the book outlines the history (best I have read so far) of Philippine postcards, from the pioneer era up to the photochrome era (1939-present). It includes the valuation of all picture postcards in the book and their grading value. It also provides an extensive list of printers/publishers of Philippine postcards during the American era and abbreviations/symbols that are commonly used for picture postcards. Best part is that most of the Philippine picture postcards are illustrated in color in reduced format." -- From a post on Facebook
