Boys and girls...I have a pair of GI socks that is probably older than many on this thread...now tell me this...I don’t recall ever hearing about font’s until the computer age....and yes I typed on manual as well as electric which there were rare in 1961, however by 1964 there were a few more. However fonts....hell you just got a typewriter and that was it.... That being said if you were in the business you probably knew about fonts, but the average person had never heard of them.
