I've seen that. I say the famous post #47 in real time and I also saw the original Executive image when it was first posted.
My point remains that the superscripted "th" could not have been done on an Executive. The Executive could not print above the font body.

I just don't recall clearly what the IBM Executive "th" looked like. It would help me if you had a link handy or just put the image in your post.
