Tokai Note, manufactured by Tokai Paper Products Co., Ltd. An art book designed by Setsuko Akamatsu. A set of two books: "Going Out Together" and "Rose Room." As a bonus, the back cover includes a "3D Pin-up." By cutting along the dotted line under the girl's collar, you can change her outfit, and by attaching the support paper, you can display it standing up. The front and back covers' insides are coloring pages. The notebook is blank and has 16 pages. The size is B5 and it is thread-bound. It is unused and has been carefully preserved, so there are almost no yellowing or stains. Setsuko Akamatsu, from the mid-1950s, serialized "Kodama Hime" in Kobunsha's monthly magazine "Shoujo," "Shiawase no Hoshi" and "Otome no Inori" in Kodansha's monthly magazine "Nakayoshi," "Minarai Tenshi," "Bara Shimai," and "Nanako" in Kodansha's "Weekly Shōjo Friend," "Aozora wa Doko ni" in Shueisha's "Weekly Margaret," and so on. She also wrote long manga one after another in Wakagi Shobo's rental book "Himawari Book" series, and was a popular artist who published personal series such as "Setsuko Akamatsu's Love Story Series" and "Setsuko Akamatsu's Mother Series" from the same company. Along with her husband, Kazuma Maki, who had a drawing style so similar that even very knowledgeable fans couldn't tell them apart, she was very active in rental book single volumes, shojo manga magazines, and Shogakukan's grade magazines from the mid-1950s to the mid-1960s. After that, she continued to provide illustrations to Showa Note, Tokai Note, Mitsubishi Pencil, etc., and was loved by girls. Judging from the illustrations, I think it's a design from the mid-1960s or later. For fans of Showa shojo manga, or those who collect stationery from this period, how about it?
