How can it be real? Seriously? Look at the two images above. One is the forgery, the other generated from MS Word TODAY. There are no visible differences in the type face, layout and orientation and that is utterly impossible to justify.
I don't have a trained eye to catch a forgery and don't know a thing about typewriters of that day and their capabilities. But supposedly CBS had them examined. They may be liberal but they wouldn't be stupid enough to pass off fakes like this. That part makes the least sense of anything.
