This is a 'hige-tsumugi' Nagoya obi
with 'sazanka'(sasanqua)-like elegant flower design, which is dyed.
Textile is exquisite Tsumugi
silk and has nubby touch with rusty atmosphere, and 'hige'(beard) threads are coming out.
There is a stamp of the designer's signature on the lower Otaiko(square bow).
Although not shown on the figure and the photo, it has some small patinas on the blank part of the belt part of the right side and a linear stain on the 'Maegara'(front patterned part) of the wrong side.
However, if you start wrapping the obi from your right tummy to left(Rotate obi counterclockwise), the stain will be hidden.
It has slight folding lines.
For the details, please refer to the photos and the sheet.
It's still wearable enough with very good condition.
This simple design will brighten up you on the scene for sure!
