A Civil War Era Photobomb

There's so much I want to find out about this picture. Did he do this on purpose? Was he just waking up? Was he an artist ahead of his time? What was his name? Did his friends find him funny?

How long did it take for his friends to realize this photobomb? Did they drink whiskey afterwards? Which side did he fight for? Why does the guy standing in the middle have his hand like that? Why does the guy sitting in the middle have such a gnarly mustache? SO MANY QUESTIONS. [Neatorama]
