The numeral "8" in the date seems to be above the baseline in the CBS document. "7" in "187th" seems to go below the baseline. Furthermore, the serifs in capiral characters seem to be a lot heavier in the CBS than in the LGF version.
That's just distortion for the document being copied and the copies being copied etc.
You need to understand that the original was supposed to be typed by a human on a typewriter.
It would have taken two or three "takes" to make sure you know when to hard-return so that you NEVER needed to hyphenate a word.
Open up word and write the "original" yourself using Times New Roman size 12 (oddly, it's the default on my version of Word... another kicker)...
Probably due to multiple copying (to make it look old) by the Democrats who gave it to CBS.
