Okay, I admit this isn't the most eloquent review, but I'm giving this book a shout-out because it is so amusing, adorable, funny. The authors classify these cartoony characters into five sections with an intro for each and an overall introduction prefacing it all. The intros were somewhat informative, not terribly deep in explanation but deep enough. I liked the variety and quantity of images they included and how their captions were set in a solid-color version of the character they are describing on that page. Great gift idea for anyone who likes Japanese pop art and cute, bubbly cartoons in general.
