As the United States commemorates the centennial of World War I, one of the nation’s premier military history institutions pays tribute to the Americans who served and the allies they fought beside to defeat a resourceful enemy with a lavishly illustrated book published in partnership with the Unites States World War One Centennial Commission. The story of WWI is told through the memorable art it spawned including posters from nations involved in the conflict and a taut narrative account of the war’s signal events, its major personalities and its tragic consequences; and the timely period photographs that illustrate the awful realities of this revolutionary conflict. Most importantly, this book is a tribute to those who served in the Army, Navy, Marine Corps and what would become the Air Force. It serves as a lasting reminder that our world ignores the history of World War I (and the ensuing WWII) at its peril lest we forget. Proceeds from the sale of this book help build the WWI Memorial in Washington D.C.
