Usborne Helicopters, Drones, Artificial Intelligence and Spying Books lot

pre owned, very gently used books. Usborne Helicopters, Drones, Artificial Intelligence and Spying Books lot. Authors are Emily Bone and Henry Brook. 4 books are Flexibound, No rips or writing, slight creases. I absolutely love Usborne Books, very informative, educational development, very interesting for kids to look through again and again. These books are not cheap, but worth it. Usborne Books are used for homeschooling and in schools as textbooks. Refer to pictures as part of description. Will be posting more books, so check my closet.
