This is a Showa-retro comic book. It's "Tasogare Toki ni Mitsuketa no" by Ako Mutsu, published by Shueisha's Ribbon Mascot Comics, a reprint from 1976. The cover has scratches, and there is soiling on the edges and top. Also, a name stamp is on the top (this is the part that has been whited out in photo 6). Please understand the above points before purchasing.
