Hey, I think I see some proportional font technology in that memo! Should I ping Buckhead?
Is he still hiding out??
Are you talking about "prosperity" [third line from the bottom]? That's not proportional spacing, that's half-spacing which many mechanical typewriters (including some I've used) support as a means of trying to squish in an extra letter semi-legibly.
Actually, it's pretty obvious that's not a fake (or at least not an incompetent fake). It uses Courier throughout, with a "jitter" in character positioning common to cheaper mechanical typewriters.
Doesn't the "obvious forgery" look of the CBS Memos.
