The following is information based on my research. Please judge from the photos. [Product Description] This is a set of two volumes, Volume 1 and Volume 2, of rubbings of "Rōgō Shiki," a masterpiece of calligraphy by Kūkai (Kōbō Daishi) from his youth, considered a treasure of calligraphy. My grandfather carefully stored them in a dark place at home. They are elegantly bound with decorative cords on a heavy purple Japanese paper binding, giving them a distinguished appearance. [Value of this Item] • First-class material for Kūkai research: "Rōgō Shiki" is the origin of Kūkai's thought and calligraphy style, and is an indispensable masterpiece for those studying calligraphy. • "Aged paper" aged for 30 years: After more than a quarter of a century, the moisture has evaporated from the paper and the fibers have settled into a "matured" state. It possesses a deep texture and dignity unique to aged paper, which cannot be found in new paper today. • For collection and as a model: In addition to being for appreciation, it is also an excellent resource for practicing calligraphy by learning the powerful brushstrokes. [Details] • Contents: Rōgō Shiki, Volume 1 and Volume 2 • Condition: Long-term storage item • Era: Published in the early Showa period • Binding: Japanese paper cover with binding cords *As this is a long-term storage item, there may be slight signs of age (e.g., minor stains) on the cover and edges.
