Created in the early 1980s, My Picture Diary is not technically comics (or manga), but rather an illustrated journal.  It records the day-to-day life of its creator, Fujiwara Maki, and the reality of her married life with Yoshihiro Tsuge, a major pioneer of literary manga, but also a sufferer of depression.  As such, it offers a fascinating counterpoint to Tsuge's work.
