Hey Bolland and Ross, let someone else have a turn!
The tug of war between those two men came down on Bolland's side in 2001 when he took another Eisner for best cover artist. That year he started doing covers for The Flash and Gotham Knights along with the covers he continued doing for Invisibles and I'm surprised at the range he used. His Flash covers are evocative of the silver age; they could almost have been used in 1960. The Gotham Knights covers tend toward the eerie and noirish as appropriate for a Batman comic. As for The Invisibles... they're about as weird as Grant Morrison so they fit right in.
