Notice how damned near every letter on the document is misformed, misshaped and any many cases run together. No typewriter does that. Hell, no word processor does that. Must be a hand forgery!
I don’t know if you were being sarcastic or not but in the fifth grade I sat at my desk, bored out of my mind, printing typefaced messages with a ball point pen. Apart from the blue ink it was nearly indiscernible from typewritten text in font and spacing.
A Buckhead moment this is not, IMO.
What I see is within the normal variability of typewritten characters mixed in with variations of pixelation from scanning. I don't see any structural variation of the fonts in question. And there is no technological smoking gun like we saw with Rathergate. To the contrary, the fonts are consistent with a manual typewriter banging out the characters.
If it is a forgery, this IMO doesn't prove it.
