One of my fellow members of Pro Imaging posted a link to these fantastic colour, sorry color, shots from WW2 era United States. Shot by Farm Security Administration or Office of War Information photographers on 35mm and larger transparancy film they exhibit not only a great eye for detail but a fantastic understanding of what was then still a very difficult medium to master. See and read more at the International Business Times.
And if you're interested in seeing more of this and other work then head to The Library of Congress where you'll find a vast collection that documents the country from the early days of photography to the modern era. And most is public domain and available for download.
