The pictures on Footnoted are public domain, CC0 or Creative Commons Attribution images. We found them on Wikimedia Commons and through Openverse, resized and cropped them, and link each one to its original page below with its author and licence.

Pictures illustrate a topic; they are not sources. The facts on each page come from the references listed at its foot. People shown in modern photographs are models or passers-by with no connection to the subjects discussed; the 1914 photograph is a historical record of the truce itself.
