Postmark: "Soisy 17-11 15 Seine", indicating it was processed on November 17, 1915, from Soisy-sous-Montmorency in the Seine department.

This envelope is indicative of the extensive network of communication needed between military hospitals and regimental depots during WWI. Convalescent hospitals like the one at Soisy-sous-Montmorency were crucial for the rehabilitation of soldiers, and communication with their units was essential for their eventual return to duty or discharge.

Condition: Given its age and historical journey, the envelope exhibits signs of wear such as fading, creases, or minor tears. The condition reflects its passage through wartime postal systems.

Historical Significance: Valuable for collectors of WWI memorabilia, particularly those focused on French military logistics, medical care during the war, or postal history. It provides a glimpse into the administrative side of soldier recovery and management. Illustrates the system in place for managing wounded or recovering soldiers, the importance of communication in military operations, and the human aspects of warfare where healing was as much a part of the war effort as fighting.

Note:  This WWI envelope not only serves as a piece of postal history but also as a reminder of the vast, yet often overlooked, support structure that was necessary for the French military during the Great War. It's a tangible piece of the narrative about the care and rehabilitation of soldiers, vital for understanding the full scope of the conflict's impact.
