Details are unknown, but... Upon researching the relationship between "Ai to Makoto" (Love and Sincerity) and milk cocoa, I found that both have connections from 1973 to 1975. "Ai to Makoto" (Original work: Ikki Kajiwara, Art: Takumi Nagayasu) is an immortal love story that was serialized in "Weekly Shonen Magazine" from 1973 to 1976, with a total circulation of over 5 million copies, and was later made into a movie. Morinaga Shoji Co., Ltd. (the current company) was established in September 1973. 1973 was the year the first oil crisis occurred. Amidst significant changes in lifestyles and food culture, Morinaga's milk cocoa became popular, associated with the image of a warm home, as a drink to provide relaxation at home and to enhance children's nutritional value. I think it's a work that reflects the times. It's old, so there is some staining. I hope a collector will want it. Not for sale Rare Showa Retro
