I'm a little confused about "The College Years" category, even in light of your entry that Clark considers himself Superman early in college...
That was revised later, so that Clark became Superman in his late junior year/early senior year of college.
Thanks, SM! I have one more monkey-trick for you :wink:
I'll be using Superboy Annual #1 (SBA) as I write this. It's not yet on the canonical sources list, either.
