LIFE online image archive that I linked above. (still linked under the gif below)

There's a ton of pictures from the LIFE archives, including a lot that (I assume) weren't published in the magazine. For example, there's this series of shots that were taken on Fremont Street...a little girl outside of the Las Vegas Club. I doubt that all of these were published in the magazine.

It's fun to browse, just using different search terms. Then, after you find a picture you like, click on the thumbnails for the related images.

To get to the main LIFE page, go to google.com; click on images (top left on menu bar); click on LIFE photo archive (right below the search box)
