This is a vintage Maru obi
with magnificent crane 'Marumon' (circle) , 'kiku'(chrysanthemum) and 'ume' (plum blossom) pattern, which is woven boldly.
Textile is silk, and it has soft touch.
Kaikiri lines are on both sides, which is also suitable for Hikinuki knot style.
Some yarns are frayed and tron in places. (second photo below the drawing image, A. C )
It is also discolor and has patinas due to its old age.
(fourth photo below the drawing image)
Parts of edges are open and has other flaws as shown on photos.
Because the fabric is weak, it cannot be worn.
It must be an amazing handicraft material!
