Thank you for viewing. This is a set of two books: "Dinosaurs: The Ultimate King Encyclopedia" and "Insects: The Ultimate King Encyclopedia." Both books do not have covers. There is marker graffiti on the spine of the dinosaur book (see photo 3). The insect book has some bending (see photo 4). There are also folds on the corners and spines (see photo 5 and later). These are for those who are okay with the condition as long as they can be read. The main bodies of the books have no tears, folds, or writing, but since this is a personal inspection, I apologize if I missed anything.
