Thank you, 2210! Very easy to understand! "Chuyu Muso: Naval Knowledge Picture Book" (1938) from Wakamoto Honpo, 16 pages, one book. This is a historical document from a time when Japan harbored ambitions toward the world, and as the Greater Japanese Empire, it replaced reality with an illusion to stir up the hopes and dreams of the people, using it as a means of unity. It's an extremely compact and easy-to-understand overview, a valuable resource. It can be said to be a precursor to illustrated explanatory books, a condensed read. - Title: Naval Knowledge Picture Book 16 pages Size: cm 15 x 10.5 - Illustrations: Color illustrations - Theme: The Japanese Navy - Condition: Age-related deterioration.
