I am telling you this justification is too good to have been done in 1969. Why would the navy have Kerry's citation typesetted when they did not with any other's?
It was probably a 5 minute job at most.
It is perfectly right and left justified with no hyphenations. The chances are about zero that this was done with a typewriter.
In my non-professional opinion, the Navy would have probably used a professional printer to create the Citations.
But a lowly National Guard officer typing memo notes to himself certainly would NOT have.
Probably best to let it go.
Because your premise is wrong. His is not the only citation that was typeset.
That's what I'm wondering too. Italicized proportional (and fully justified) type would have been extremely uncommon in 1969. Hell, I was born in 1969 and my birth certificate was typed. I'm more interested in the PDF that shows the silver star with a V.
