America Thanks you.
Well, thanks, but it's premature. It's not 100% conclusive because the IBM Executive and IBM Selectric Composer would do proportional fonts. The Composer was almost certainly not used in this case - it was for typesetting for camera ready and was a monumental pain in the rear to use. The Executive is possible, but still not very likely, but that doesn't resolve the other circumstances indicating forgery. As this gets sifted through the day we will eventually come to find out the truth. There's thousands of people working on it now. It's pretty cool how its unfolded.
Applause to you also.
