Note: Check out "Letters of Note".

Just tuned into Letters of Note. It's a great site that, in there own words "is an attempt to gather and sort fascinating letters, postcards, telegrams, faxes, and memos. Scans/photos where possible. Fakes will be sneered at". The letters and whatnot usually involve some famous/infamous fgure/celebrity. They range from the touching to the obscene, the quirky to the down-right educational. Enjoy.
