This is volumes 1 through 12 of "Race Pigeon 0777" by Koichi Iimori. Volume 1 and Volume 4 have the author's signature and illustrations. Volume 10 is missing its cover. The condition of the books includes yellowing, stains, and tears in the covers. Volume 10 is missing its cover (please see the photos). Koichi Iimori was a classmate of mine in high school (he passed away 17 years ago). This book was brought to me by Iimori a few years after he debuted as a manga artist. It's a book filled with memories of him, and I'm very fond of it. The reason I'm putting this beloved book up for sale on Mercari is simply because if I just kept it on the bookshelf and, belatedly, followed Iimori, this book would disappear without seeing the light of day. So, I decided to let it go from my hands.
