(from ebookjapan):

Mangaka Toshiko Ueda, born in 1917 (Taisho 6) and died in 2008 (Heisei 20). This is a story about a real tough woman
who paved the way for female mangaka, a path that no one had yet taken.

It can be said that the "history of women manga" in Japan began before the war, when a crazy girl named Toshiko Ueda
made an imaginary picture in the high and wide sky of Harbin, Manchuria.
Motoka Murakami puts his all into this book, the Blue Spring of manga.

The long-awaited first volume in tankoban form!
