This is a vintage Maru obi
circle and 'housouge'(large karabana flower) pattern, which is woven.
The large and colorful pattern is high impact.
Textile is exquisite soft silk.
It seems like the original owner tied it with variety ways of tying. So that, it has folding lines throughout.
There are some other flaws such as faint stain (see the 2nd photo of flaw photos.) and slight discoloration on the background.
(The brown stain on the wrong side of 'tesaki'(narrow end) is noticeable.)
For the details, please refer to the photos and sheet.
If you don't mind those minor flaws, it is still in good condition to wear.
Please enjoy the vintage dynamic design!
