One big case of the artist doing the writer's job is back in the first issue of Claremont/Byrne's "Dark Pheonix." On the first appearance of Kitty Pryde, her speech and actions in the story show very little about who she is. The ART, on the other hand, characterizes her perfectly: she has a star of David, and a big giant teddy bear behind her in her bedroom. (This is an example of characterization through art: what kind of a girl would have a big giant teddy bear with a bow on their neck in their room?)
While somewhat off-topic, with moderator indulgence please, let me speak to this.
A star of David tells us nothing about Kitty's character except that she's Jewish. She could be one of those really nice Jews that you'd like to be friends with. Or she could be an elitist, self-entitled kind of Jew who wouldn't want to be friends with you unless you were Jewish too. That star tells us nothing about her character. (Yes, I used to work at a Jewish facility, got really close and was friends with one of the families there. But once they learned I wasn't Jewish, they wanted nothing further to do with me.)
(Similarly, a crucifix on a girl doesn't tell us anything about her character either. She could be a wonderful person. She could be an uppity snob. She could be just into crucifixes as fashion accessories. You get the picture.)
While not all girls/women have stuffed animals, esp. giant ones, most of them I know adore the cuddly things. Given the chance, most females I know would jump at the chance to own such a toy. Again, this tells us nothing about Kitty except either her family is rich enough to be able to afford such a neat toy or she had a rich friend who gave it to her. Or maybe she won it at a carnival. Or she found it. Or she made it. Or someone made it for her. Or ... (I bought a giant Snuffles for my girlfriend and it cost me about $300 plus tax, so Kitty's bear is not a cheap bedroom toy.)
