I don't get it

Here are the new documents about Bush's flight status.

Supposedly, these are the originals from 1972?
But NOBODY used Times Roman justified typeface fonts in 1972 -- particularly in personal memos for files.
Nobody used "fonts" at all, except typographers in printing plants.
What we had was: Courier 12 point And that's what everyone used.
In an office situation, writing a note for a file, at best you would get a typewritten note, maybe on an electric typewriter but more likely on a manual. These notes would have been typed by the office secretary, whose initials would be at the end of the memo. Much more likely that a note to file generated by the executive himself would have been handwritten, because most men could not type at all.
