This antique postcard beautifully captures the romance and patriotic spirit of the early 20th-century French military. The man in the postcard is dressed in the distinctive light blue jacket with red trim and trousers, a uniform that dates from 1917 during the heart of World War 1. An earlier version of this uniform featured red pants. As the war progressed, the French military recognized the need for more practical uniforms, leading to the adoption of the “horizon blue” attire by 1915. This shift marked a significant change in military history, reflecting the harsh realities of modern warfare and the need for camouflage in the trenches. The collar style is distinct from 1917.
