Working on the Benjamin Franklinstein books with Larry over the past year or so, inventors have been on my mind a lot. That’s why it was so interesting to come across these samples of letterhead from two of history’s greatest, Thomas Edison and Nikola Tesla. The two were not great friends, and it’s interesting to see how their personalities came across in the way they chose to correspond with the public. (I know which one I’d rather receive a letter from.)
