As Leon's post shows us, there is a Christy Mathewson in the set. I also noticed this checklist on the prewarcards.com site:

This list also indicates that an Ed Murphy card exists, which makes it 15 cards that have previously been identified as part of the issue.
Also Anson in his article mentions that the self-developing aspect has never been confirmed. I have some doubts that these cards were self-developing, as their images are much too strong compared to other self-developing cards (for example the Tattoo Orbits).
