As we move further and further away from the need for a pen and paper, with cell phones capable of handling our daily checklists, emails more common than writing a letter, and the ease of editing the drafts of a paper on a computer, hand-written manuscripts are becoming a thing of the past. This week’s Tumblr Treasure is a historical trip to the times when you could recognize a friend by his handwriting. F*** Yeah Manuscripts is a Tumblr compilation of manuscripts and other hand-written treasures from some of the greatest authors and occasional historical figures of all time. After you’ve scrolled through our tiny collection, be sure to show them some Tumblr love by clicking on the link above and check out the Visual News Tumblr while you’re at it!
