Fine example of the Japanese aesthetic of "suggested beauty" where the patterning extends beyond the edge of the scene so that the viewer can fill in the rest with his or her imagination. Lovely design of butterflies outlined in red and filled with a floral design in light pastels and silver. An undulating wave pattern behind.
As with most white or cream colored vintage pieces, there is some blemishing from age and in this case one spot of discoloration, see photos. Still would make a beautiful display or obi if worn with a formal kimono.
This is a fukuro obi - wide for the entire length, plain on the backside and a patterned design only on the front. There is a one yard "blank" section on the front, as is common with contemporary fukuro obi, where some cost can be saved by leaving it blank where the first wrap layer of the belt portion occurs, since it doesn't show to the public.
