The origin and evolution of the United States flag;
A 1915 historical monograph by R. C. Ballard Thruston, issued in Washington under the Sons of the American Revolution, tracing the development of the United States flag for patriotic societies and government readers. The plates are halftone photographs of surviving flags and banners hung against plain grounds, showing varied star counts and arrangements, swallow-tailed cavalry guidons, creased and torn cloth, and pikes with spear finials \u2014 useful for star-field layouts, period stripe proportions, and textures of worn fabric.
