Captain, by Akio Chiba, is available in both paperback and hardcover editions for volumes 1, 2, 4, 6, 8, 9, 10, 21, and 25. Play Ball, also by the same author, is available in both paperback and hardcover editions for volumes 1, 4, 9, 11, 14, 15, and 19. I haven't been able to collect them all at once, so the book sizes and volumes are mixed. There is some yellowing and soiling, but they are readable. For those who want to read those masterpieces even if they are incomplete, please consider them.
