I was reading the Jezebel blog (see right on the good blog list) and found this most excellent addition to the internet! Life magazine has archived their entire photo collection on google. Over 10 million, relatively high res photographs.
Here's a screen grab of the opening google page.
You have to type in the url to get to this page. AMAZING!!! The following photos are a few Jezebel posted that are quite lovely hairstyles as well as lady truck drivers from the 40s!
Just think of the possibilities!
