That's an incredible set of photographs. Only a few probably quality as "great photographs" in any artistic sense, but the documentary value of stuff like this is just overwhelming. Color photos were obviously relatively rare in those days. Now they're ubiquitous. I wonder how people will view photographs from today (when there are so many zillions of them around) in another 70-80 years. Just seeing the differences in products, landscapes, homes, clothes, EVERYTHING is fascinating.
I love old photos in general....especially just plain old "slice of life" snapshots like these. What really strikes me about them is the work I go to to make my photos look like this (color-wise) and they get it straight out of the camera....LOL.
Not sure if this site is known, but it's a great site for old photos scanned a very high resolution. If you download the "high resolution" version, you can easily enlarge to a 5x7 using Photoshop's resize. It also offers a great search engine.
