Did anyone notice that the "i" in "received" (last sentence of memo) is lower than the other letters? Why? To make it look more like a typewriter had been used? If so, then look at every other "i" in the memo. None of them, not a single other one, is lower than the others.
It's pretty clear to me that the document was "aged" by faxing it and photocopying it a few times. The faxing process can cause letters to offset slightly due to the fax's low resolution and slightly misaligned page.
