I started following Welcome To The Typosphere not long ago. It is a blog dedicated to typewriters. I was still using my mom's 1942 Underwood manual typewriter before I could afford a PC back in the days. WTTT posted this 1944 Navy typing training film from the Internet Archive. In addition to a quick review of the development of the typewriter (in which my Underwood makes an appearance), this film instructs "women and girls" on the proper methods of typing so their work can be "as important" as work done by men. Bear in mind, it is a 1944 military training film. Enough said.
