This is a three-part penmanship series by Sensei Shikako Takami. From oldest to newest publication year, the books are: "Penmanship Model Letter Writing," "Penmanship for Women's Letter Writing," and "Business Horizontal Penmanship Letter Writing." The images show the front cover, back cover, table of contents, example text, the page in the worst condition, and publication information, in that order. I will add more detailed descriptions later, but for now, I'll just leave this here. Kosetsu Takada Shifukai Pen Era Pilot Penmanship B System
