This is a complete set of volumes 1-20. It comes with the box set slipcases 2 & 3, but the box sets don't come with the original posters. The boxes are in decent condition with some corner and edge wear. The books are in good to very good condition. There is some wear on the cover/spine of some books. There is some yellowing of the pages of volumes 1-8. NOT ex-library copies. See photos to view its condition. The last photos show some of the worst flaws/damage that were found.
