I love Yoko Sano's illustrations, and this is a children's book I bought a long time ago. I purchased this book about 40 years ago. The paper is yellowed with age, but I think the inside is in relatively good condition (in my opinion). The cover has some scuffing, but the main body is clean. It's a picture book featuring animal characters, and you can enjoy a heartwarming story. - Title: Nebokete Nankai Arimasen yo (I'm Not Sleepy At All) - Author: Kei Moriyama - Illustrator: Yoko Sano - Genre: Picture Book - Features: Illustrations of animal characters - Condition: Slight scuffing on the cover Thank you.
