Color images, from before there was color (or much color)

These are fascinating.  Normally the images we see from this period are in black and white.  But this collection is a color view of life in the early 40's.  These pictures were taken by members of the Farm Security Administration and capture a post depression rural America in rich color.  There's something fascinating about looking at these images.
