This is a koto cover, which has charming girls picture, which is dyed colorfully.
From the signature, it seemed to be drawn by Kacho Ikuta, one of the famous Japanese-style painters.
Textile is exquisite silk, and has very soft touch.
It has some flaws as photos show, but as a whole it is in very good condition.
