Over 150 never before published illustrations, complimented by an exhaustively researched text, document the little-known air war between Bolivia and Paraguay during the late 1920s and early 1930s. Full details of such aircraft as Fiat C R 20s, Curtiss Hawk IIs, Curtiss Ospreys, Potez 25s and all other types employed by both combatants, including acquisition, operations, and markings make this a must for historians, modellers, and anyone interested in golden-age aviation.
