Who ever created these forgeries is likely to be someone under 40 years of age who never even thought about little details like proportional fonts. If they were going to create a half decent forgery they should at least have chosen a font like courier!
Remember all those detective dramas of the 50's, 60's, and 70's. A good detective would even figure out which typewriter was used to type a letter based on the crud that built up in the keys.
The Selectric had proportional fonts.
We didn't HAVE schmiggly wiggly MONITORS!!! And weeeeeee LIKED it!!!!
Someone just posted that Selectrics were standard then in the milatary.
