This is a Gundam plastic model mook (magazine-book), Mobile Suit Gundam/Gundam Weapons [Master Grade Model] Gundam Mk-II & Super Gundam edition. There is some discoloration, scratches, and wear due to age, but it is still readable. Please refrain from purchasing if you are overly concerned about the condition. This is one of several old Gundam plastic model books I have. For Gundam and Gunpla fans!
