絵本保元平治物語
This is a Japanese ehon picture book, the Edo-era Ehon Hōgen Heiji Monogatari by Akisato Ritō, reissued by Kakusei-sha in 1884 for general readers of printed illustrated narrative. The pictures are woodblock-style black-and-white battle and court scenes, scanned sideways, with dense figures in armour and flowing robes, dramatic diagonal horses and swords, and vertical columns of Japanese text that a designer might borrow for compositional energy and ink-line dynamism.
