I purchased the 50th-anniversary book new last year and have kept it at home. It's generally clean, but there are minor scratches from use, so please refrain from purchasing if you are concerned. It's a set sale with the spin-off. The spin-off is a comic. I just bought the spin-off as a used item on Mercari last year, and since it's been quite a while since its release, there is some aging as shown in the photos. If you want to read them, please do! This is a set sale, not sold separately. Please consider purchasing only if you understand that these are used items.
