The name of the person who received them as a gift is written in marker on the top of the TV version and on the side of the Mecha Encyclopedia. Also, each book has some warping. The Mecha Encyclopedia has a tear on the cover that has been repaired with tape. It appears the cover and the book are secured with tape. As a result, there are tape stains on the book.
