This is an elegant vintage Maru obi
with flower such as 'kiku'(chrysanthemum), 'matsu'(pine tree) and 'Tachibana'(Japanese green citrus) on jigami'(fan shape) and 'yukiwa'(snow crystal), which is woven on the yellowish light gray background.
The vibrant pattern emerges out against the sedate colored background.
Textile is silk and jinken (rayon) blend, and has soft touch.
The pattern at otaiko(square bow) part is designed upside down from kaikiri-line(end mark line) to be tied with hikinuki style.
It has patinas overall.(3rd flaw photo)
There are other flaws such as a folding line(6th flaw photo) and discoloration overall.
Please check detail photos.
Unfortunately, it is no longer wearable due to the fabric is getting weak.
However, please enjoy its full taste of vintage!
