A letter set featuring designs from Kyoko Hikawa's "Chizumi and Fujimi Series," which was serialized intermittently in Hakusensha's "LaLa" from 1979 to 1985. This was a special bonus for the "LaLa" May 1980 special issue. The writing paper is A5 size. The cover (full color, see photo 2) features Chizumi making mascot dolls of herself and Fujimi with a sewing kit, and Fujimi looking at his own mascot doll. The writing paper pad (see photo 3) has an illustration of Chizumi showing the two mascot dolls to Fujimi, who is standing below a high wall. It is printed in two colors, blue and pink, and there are 20 sheets. The envelopes (see photos 4-5) feature a simplified version of the writing paper pad design. They are printed in two colors, blue and pink, and there are 4 envelopes. The stamp area has a comical illustration of Fujimi's mascot doll looking at Chizumi's mascot doll, whose strings are tangled, making it difficult to move. It makes you feel like you don't want to put a stamp on it. It is new and unused, only taken out of the bag once, but there are some stains on the pad due to age. However, considering it's a 45-year-old bonus, the condition is very good. Kyoko Hikawa debuted with "Akikaze Yurete" published in "LaLa" in 1979, and has continued to publish masterpieces in "LaLa" and "MELODY," including "Hoshi no Harmony," "Shiroi Mado no Mukougawa," "Kouya no Tenshi-domo," "Otogi Moyou Ayanishiki," "Kanata Kara," and "Mahou ni Kakatta Shingakki." The "Chizumi and Fujimi Series" was very popular, with nine works published: "Akikaze Yurete," "Haru no Hitokakera," "Triangle Travel," "Haru wo Matsu Koro," "Parasol Essay," "Sweet Color no Kaze no Naka," "Pastel Kibun," "Gingko Namiki Kara," and "Giniro Ehon." For Kyoko Hikawa fans and fans of Showa-era shojo manga, what do you think?
