On another note, what do you think of the superscript in this:
The second line has 111th with the superscript th, and was dated 1968. All the rest have 111th with no superscript. They were obviously written on different typewriters at different times, but it obviously was possible to get a superscript in 1968, as these are official docs.
Here's a link to the doc from the records Bush released. see page 3: http://www.usatoday.com/news/bushdocs/9-Miscellaneous.pdf
The th is underlined. Nonunderlined th not available is my understanding.
