I also posted this to Buckhead:

You're absolutely correct. I just looked at the files, and they don't pass the smell test. Most typewritten items from that era would have been in Courier font. And why would these items be copies, anyway, if these memos were for the guy's own personal file? They wouldn't have that run through the copy machine a zillion times aura to them in that case.

Mrs. Steveo used to underwrite mortgage loans. When a loan officer wanted to overstate income they would alter pay stubs and photocopy multiple times to generate copy noise and hide the alterations. It never worked because they never went through the trouble of checking the noise for randomness.

If you examine the 04 May 1972 and the 18 August 1973 you'll see enough similarities in the noise background to question their authenticity.
