Some pictures were meant to make history and some weren’t. But you never take a second look at those that didn’t mean anything. So be it in the nature of the situation or because it has famous persons in it, a good picture is recognizable in an instant. I bet the guy who took a photo of Charlie Chaplin and Albert Einstein together knew he was making history right at that moment. And most probably a lot of the people who photographed these other pictures here knew it too.
