I have a concern about the first page of that PDF. Were italicized proportional fonts (kerning built in) around in 1969? It's odd because the second page shows the correct monotype for that time period. Notice, too, that the first page has typed letters at the bottom that are also monotype. Why would one document contain two different type styles?

Of course it did. Typesetters could do all sorts of things. Look, people, the Killian forgery scandal arises from the fact that they were supposedly composed on a typewriter which is far less capable than a typesetter.

There is no "correct" monotype. There were plenty of fonts to choose from in that time period.

Umm, because it can?
