This original vintage real photo postcard (RPPC) depicts a group of five World War I era U.S. Army officers, likely members of Battery B, posed outdoors in full uniform. The men stand in formation on a grassy field with trees in the background, suggesting a stateside training encampment—possibly at a National Guard mobilization site or artillery training ground prior to overseas service. Each soldier is dressed in standard U.S. Army Model 1912–1917 uniforms, which include: khaki or olive-drab wool shirts with buttoned breast pockets, breeches tucked into tall leather puttees or riding boots, wide web belts with ammunition pouches and holstered sidearms, and campaign hats (the flat-brimmed “Montana peak” style) that became a visual hallmark of the WWI Doughboy period. Several of the men wear Sam Browne belts and sidearms—clear indicators of officer rank. Their confident stances and self-assured gazes support the identification as officers, likely from an artillery or training detachment given the notation “Battery B.” Their expressions vary slightly—from steady professionalism to faint amusement—capturing the camaraderie and seriousness of men preparing for active duty in the Great War. The photograph is well composed, showing crisp detail in the folds of the uniforms and the shine of their boots. The card exhibits light corner wear typical of its age but retains strong contrast and focus throughout. The reverse of the postcard features the AZO stamp box with all four triangles pointing upward. This paper style dates the card to approximately 1904–1918, perfectly aligning with the World War I era and confirming its period authenticity. Photographs such as this were often made by local or camp photographers as souvenirs or documentation of training and officer corps gatherings. While the specific regiment here is not named, the men’s uniforms and equipment are textbook examples of the American Expeditionary Forces officer class. This RPPC is in good antique condition with minor corner wear, a small creases in the corners, and slight surface toning consistent with age. The image remains clear and rich in tonal range. The reverse is unused. See Scans.
