This is a set of two picture books by Leo and Diane Dillon, a representative picture book duo from America. Why Mosquitoes Buzz in People's Ears Based on an African folktale, this picture book humorously depicts the misunderstandings and chain of events among animals. Who's in Rabbit's House? Based on a folktale, this book is illustrated with a unique, mask-like performance, making it feel like you're watching a real play. Price is not negotiable. I have checked the inside briefly. In my opinion, the condition is good. Recommended for those who understand that these are used books. Please refrain from purchasing if you are sensitive to condition. Packaging will use recycled materials, with simple wrapping in plastic only, and will be shipped via Yu-Packet Post.
