Just found a nifty Google feature. Go here for the home page of the listings of all Life magazines from 1935 to 1972. Under "about this magazine" they give free access to share, print and post images for personal use. There's also a world map with red pins marking places mentioned in the magazine you designate. When you click on Contents the list of articles in that magazine come up. You can view full screen, two pages up, or four pages up.
I discovered this from World magazine's article, "Googly eyes," which states you can do an image search by appending "source:life" and the search will be limited to Life archives. Without that nice URL you can just go to Google's homepage, click on More, then click on Books. Magazines are shown, as well as books.
