What you see now is a new picture book, the content of which is the same as in the past. It is no longer printed the year before, but reprinted (but not redrawn, just scanned and copied on the basis of the book printed by the boss the year before) and then printed.
The key to pure appreciation of picture books is to look at the painter, what year the collection should be published, what it looks like, which painter painted it, the layout of the book, the number of books published, whether it won prizes, and so on.
At present, the published comic books are overpriced. After all, they are replicas, and their collection value is not great, that is, there is not much room for appreciation in the future.
