There are some faint spots and folds on the drawing part.
Although, the condition of this scroll is not bad.
A four-character Kanji idiom is drawn powerfully using Japanese Fude brush
and black Sumi ink.
The idiom means that "Overconfidence can be very dangerous".
This calligraphy was done when Sojun was serving as the chief priest of
the Tokai-Ji Temple.
The endorsement written by Shino Chikuin on the lid of wooden box proves
the drawing was certainly done by Keiso Sojun.
However, the personal history of Shino Chikuin is unspecified at all.
