This is a vintage Maru obi
with 'mukai-onagadori'(pair long tail bird) and 'kiri'(paulownia) arabesque on diamond pattern, which are woven.
Gold and silver foil threads parts are elegantly shining.
Textile is exquisite silk and has soft touch.
The pattern is set upside down, and it's to be tied in 'hikinuki' style.
It has patinas and discolorations all over due to its age.
There are some snags on pattern in places.
Smudges between tare and otaiko part is not so prominent.
There are some other flaws including folding lines and frays on both ends.
Please check photos and a figure for details.
Enjoy this gorgeous classical design on vintage kimonos!
