This is a set of two picture books by Leo and Diane Dillon, a renowned American picture book duo. 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 presentation, 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 be a simple wrapping with only a plastic cover, using recycled materials, and will be shipped via Yu-Packet Post.
