The U.S. War Department Commission on Training Camp Activities issued this Army Song Book "For free distribution to all Officers and Men in the Army" in 1918. The nation, of course, still battled in the throes of World War I. Doubtless Army song books such as this helped boost morale. The book includes words and music to the U.S. National Anthem and other well-known songs as well as the anthems of America's allies at that time including Great Britain, France, and Belgium. Pocket-sized, the cover is well camoflaged in a dull khaki brown.
