I don't have Kevin Eastman's "Artobiography" close at hand to check, but it is possible he may have printed this document in it. Regardless, I thought it was interesting enough to post.
I found this while going through my folder of stuff from the Raphael "One Issue Micro-Series". This is the typed page which I got from Kevin when he was plotting out that issue, the one which introduced the character of "Casey Jones". There's no date on it, but it's probably from some time in late 1984 or 1985. -- PL
