Mr. Men and Little Miss4

The Mr. Men and Little Miss series is a collection of children's books created by British author Roger Hargreaves. Each book features a different character with a distinct personality trait, represented in a simple, colorful, and cartoonish style. The characters are drawn with bold outlines, bright primary colors, and minimalistic designs, making them easily recognizable.

The Mr. Men characters, such as Mr. Happy, Mr. Bump, and Mr. Tickle, often have round or square shapes, exaggerated features, and simple facial expressions that match their personalities. Similarly, the Little Miss characters, including Little Miss Sunshine, Little Miss Chatterbox, and Little Miss Naughty, share the same simplistic yet expressive style.
