Looks like it! This is a set of 23 books: volumes 4, 7, 8, 9, 10, 12~16, and 18~30. The earlier volumes are about 30 years old, so they show some signs of aging. They have been stored in a bookshelf with a door, so the covers are relatively clean. *Individual sales are negotiable. However, priority will be given to those who purchase the set outright, even during negotiations.
