I recently stumbled upon a website some of you may or may not know about called Letters of Note. Here is their short about description:
Letters of Note is an attempt to gather and sort fascinating letters, postcards, telegrams, faxes, and memos. Scans/photos where possible. Fakes will be sneered at. Updated as often as possible; usually each weekday.
I personally find things like this really fascinating, especially as someone who is interested in pursing archives. They’re like snippets of history that you can view. One that caught my attention was a love letter written by a pregnant widow.
