I've recently become more and more attracted to letters from persons that I have an autographic interest in. I now have an Alfred Hitchcock typed letter from 1940 in which he discusses his budding American film career with an assistant director. It's simply signed "Hitch" in black fountain pen ink.
Some may not be interested in something like a TLS since there is not much "ink" on the page but I am fascinated by the content. I also have my eye on a TLS from John Ford from the same era in which he engages in a bit of gossip about an actor who he finds to be too melodramatic for a part he is casting. This one is signed "Jack" with no surname.
Of course there is so much material from literary and historical figures in typed letters. I'm curious if other members here are interested in this format. Or does the lack of actual handwriting not hold much interest?
