stumbled upon this today: letters of note
it's basically just different correspondence that people submit, but it's really good correspondence.
like this letter to president roosevelt from a ten year girl whose last name starts with a 'w'. she suggested that roosevelt begin drafting fathers alphabetically, so that her father wouldn't have to go to war.
or this response letter from john kricfalusi--the creator of ren and stimpy--to a young artist(from toronto). the letter is 8 pages long, handwritten, and gives the young artist instruction on how to become a better cartoonist.
this letter from nikola tesla, a response to the red cross.
and this letter from a soldier in 1942 to his daughter, for her future birthdays.
