John Romita, Jr. is a great pick to be the artist on the brand-new "old school" Avengers book by Bendis.
Romita Jr. is still a great modern artist, but as a guy who has been working at Marvel for over thirty years now, he certainly can be termed "old school," as well. So it is a great choice for the return of the "classic" Avengers - modern and old school at the same time. Very clever.
Not only that, but note that with Bucky as the Captain America of this new team, it still has a bit of that "not totally old school" edge to it.
So far, so good, Marvel!
