Really Big Pictures

There is a site called Shorpy which sells prints of vintage images from the Library of Congress and other sources. The prints are a good deal, reasonably priced, and they're probably very well printed and suitable for framing and hanging on the wall.

What else is really nice about the site is that it has mounted hi-rez images of the photos that it sells. Thousands of photographs in fact, with some by Walker Evans, Ansel Adams, Lewis Hines, Dorothea Lange and other well-known photographers. Since it covers the 1850s to the 1950s, you can look at it as one of those "Way We Were" sort of projects with fascinating images from World War II, the Civil War and of course much that is non-war but doesn't fall into an easily defined historical category.

And if they keep adding 4 images a day, in about 8,587 years, they will have posted every image the Library has.

By the way, the Library of Congress is also a fantastic place to view hi-rez imagery.
