I know I've already mentioned some of these books, but it's worth pointing out that there's basically a once-in-a-lifetime opportunity to acquire a stellar run of Superman comics from the Golden Age. If you were to win the best available copy of each Superman book listed in this auction you would have the #2 Superman #1-423 registry set. You would also, likely, have a number of copies that would compete with anything in the Edgar church collection for the title of highest graded copies. the 9.8s are an obvious candidate for that, but the multiple 9.6s would be as well.
It's an exciting run.
