A few years ago I stumbled across Letters of Note, and I was instantly blown away. Shaun Usher (the creator) gathered up many, many images of handwritten and typed letters that were either famous, b famous people, or simply just wonderful on their own. If you haven't checked out the site, http://www.lettersofnote.com, go do it now. You will probably spend the next few hours there. The "most read" list on the right is a good place to start.
On December 2nd, Shaun launched another awesome, paper-based website, Lists of Note. And it's exactly what you think. So far there is a list of Francis Ford Coppola's casting choices for the Godfather, John Wayne's favorite actors and films, and Harry Houdini's rider.
This one was great too. A to-do list by Johnny Cash that inspired the site.
