This is a summer Ro Nagoya obi
with calla like plant motif, which is dyed in Sumie-like touch.
Textile is silk, and it has soft to the touch.
There is a signature and a stamp of the dyer on Tare end.
There are slight and fine stains above Otaiko pattern. (sorry no photos)
It also has tiny snags on Tare end.
Stains on lining of Maegara and the belt part transfer to the main fabric of both sides. (third photo below the drawing image)
It has some other flaws, such as patinas and slight folding lines, as shown on photos.
Please see photos for details.
Because of the stains on Maegara, it may be unsuitable for wearing, however, it still is a very lovely obi.
