This is an impressive vintage Maru obi
with 'wakamatsu'(young pine) and 'kiku'(chrysanthemum) on weave and 'kikko'(tortoise shell) pattern, which is woven.
Gold foil threads woven in the pattern are gorgeously shining.
Textile is jinken (rayon) and has rather crisp touch.
Although not shown on the photo and figure, it has tiny patinas overall.
The stains on the tare end may be bothering when tied.
There are other flaws such as rather prominent folding lines and discoloration overall.
Please check detail photos.
Though it has some flaws by ages, please enjoy its full taste of vintage!
