Writers/Artists tend to work together a lot, especially if they're good friends. Sometimes, they're indeed friends. Sometimes, it's just a matter of business. Whatever the case, what are the notable examples of such duos, often doing multiple projects together or at least having a major landmark run that only seemed possible by the duo?
Some that come to mind:
Stan Lee/Jack Kirby
Marv Wolfman/George Perez
Chris Claremont/John Byrne
Tom DeFalco/Ron Frenz
Alan Moore/Dave Gibbons
Garth Ennis/Steve Dillon
Brian Michael Bendis/Mark Bagley
Kieron Gillen/Jamie McKelvie
Who else is of note?
