For me those photos really help breathe life into that period of time, making it appear as more than just a series of abstract Wikipedia articles. Look at the contrast of those soldiers waiting next to a railroad against the fine architecture of the downtown. Today some of those folks are someone's feeble old grandpa telling stories of the old days, but look at how young and full of life they were in those pictures.

I'm a little disappointed that the top comment chain consists of belaboring the finer points of copyright statutes.
