The Walk Around/On Deck series is about the details of specific military equipment using color and black-and-white archival photographs and photographs of in-service, preserved, and restored equipment. Walk Around titles are devoted to aircraft and miltary vehicles, while On Deck titles are devoted to warships. They are picture books of 80 pages, focusing on operational equipment, not one-off or experimental subjects.

The United States used two main wheeled amphibians during WWII: the 1/4 ton GPA and the 2-1/2 ton DUKW. Although the former was a Ford Motor Company product and the later carried the label of arch-rival General Motors (GM), the two bore a similarity due to their common naval architect, Roderick Stephens, the 1937 America's Cup winner. Stephens worked for the Office of Scientific Research and Development (OSRD) and designed the hulls of both the GPA and the DUKW.

Includes photos and detailed captions of the Ford GPA exterior, interior, and engine; the GMC DUKW-353 exterior, interior, and engine. Soft cover. 80 pages.
