The Visual History Series are single-subject reference books featuring a historical introduction followed by extensive black-and-white period and walk-around photographs, many of which are otherwise unpublished. Subjects are primarily focused on armor and soft skins, but also include aircraft and ships. The Visual History Series are typically soft-cover, but the line has recently been enlarged to include the "Expanded Visual History Series" of 168-page hard cover titles. Whether you are looking for reference material or are simply a military enthusiast, you will find these volumes to be indispensable additions to your library.
