A viscount in the Armored Cavalry Branch of the French Army left behind a collection of hundreds of glass plates taken during World War One that have never been published until now. The images, taken by an unknown photographer, focus on the daily life of soldiers in the trenches.
The photographs were found by a Reuters employee who remembered there were suitcases full of stereoscopic glass plates from WWI in her family's home.
2014 marks the 100th anniversary of the start of WWI.
