I would add:
Marshall Rogers. When I think of the definitive Batman, I think of his incredible work in ‘Tec. His work on Mister Miracle was also excellent and a welcomed upgrade from Kirby’s work on the title.
Dale Keown is missing from the list- best Hulk artist ever!
Mike Grell’s work on Warlord and Jon Sable is far superior to many of the artists on the OP’s list and he should be included.
Frank Brunner is another great artist who should be included on the list
Don Rosa, the heir apparent to Carl Barks, wrote and illustrated some excellent Ducks stories in his own right, but he also wrote and illustrated the greatest origin story of all time: The Life and Times of Scrooge McDuck. If you haven’t read it yet, do yourself a favour and pick up a copy. You’ll be glad you did. It’s a timeless tale for kids of all ages.
