Thanks for looking! This sale is for one antique postcard from a collection of images of damage in the French town of Chateau-Thierry from bombardment in WWI. These were published by Jacques Marcel Delboy, a young photographer from Bordeaux, after the war. This card is titled "The bridge over the Marne". These sepia toned cards measure roughly 5.5" x 3.5" and are in good condition for being around 100 years old. 
If you have any questions, just ask! I will combine shipping on all postcards and paper items.
