The covers show minor fading on volume 6 only, corner wear on volume 13, and minor tears along the top and bottom edges of the spines throughout. About half of the volumes have light yellowing. Due to the printing technology of the time, volumes up to 5 have loose binding and a tendency to open, which is an early characteristic. However, none of the volumes show any significant splitting, and from volume 6 onwards, where printing technology improved, there is no splitting at all. Therefore, it can be stated that all volumes are in a condition where there is no splitting. Overall, the condition is surprisingly good for a first edition. While even reprints of "Mataro ga Makaritoru" are often in poor condition, an all-first-edition set with minimal damage to both covers and the main body is rare. This set is more than sufficient to satisfy collectors. Furthermore, advertisements from the time of shipment are included in about half of the volumes, making them of significant historical value. The pamphlets are not randomly inserted; the volume number corresponds to the advertisement. For example, the advertisement in volume 4 mentions "Mataro ga Kuru ①〜④," confirming that it is from the time of shipment. Considering this, the fact that pamphlets from the time are included in the rare and hard-to-find volumes 1 and 2 is a miracle and significantly increases the value of this set. Moreover, the condition of volumes 1 and 2 is better than any first edition of "Mataro" I have seen. It is easy to imagine that assembling a set of this quality would require an astronomical amount of time and a vast expense, a truly arduous undertaking. I won't mince words: it's wise to seize this opportunity. If you collect bit by bit, you might eventually get a set like this... Unfortunately, if you miss this chance, it won't come again. I must emphasize that.
