This is a photograph of some American troops taken during World War Two. I don't know exactly where it was taken, when it was taken or, indeed, who was responsible for capturing this moment in time. It came to me via that most modern of commercial conduits - eBay: a service which allows you to buy dollops of history for loose change. The very anonymity of the image provides you with a sort of freedom to explore - there is no one face you are connected to, there is no known tragedy to taint your investigation.
Cropping changes the context, creating a more focused image. Whilst the first image is about wartime logistics, the second is about wartime troops.
And the third is about people, people caught in a moment of time. A moment of war.
In case you are wondering where my Sepia Saturday contribution is this week, it will appear late on Sepia Sunday, for reasons that will become apparent then.
