Graphic novels are particularly good for books that are set during different points in history. It's a great way to get a glimpse of what the world really looked like. I have to love a book that almost perfectly depicts the family room in my parents' house! (And yes. Bowls of ice cream every night while watching television. Because we didn't serve dessert WITH dinner. To this day, my father thinks this makes sense.) The clothes were also on point, although Sunny's fashion sense was a little more subdued than mine!
The Holms do a great job with Squish, Babymouse, and Sunny, and I'm always hoping they come up with another new character!
