Sometimes you don't know who the subject of the picture is. We all have them. Photos on the margin of our knowledge, faces we don't recognise. A man in uniform stares challengingly into the camera. There is no clue as to who it might be. On the back of the photo the following words are written. "This is from one taken over twelve months ago, he does not look so ill and weary on this. I have had to wait for this one taking off another." It was obviously taken during the Great War. Did he try and stare down death in the same way. Who knows. Sometimes you just don't know. Sometimes you don't want to.
