A massive koinobori (carp windsock banner)
Cotton
From the early Showa era
Approximately 348cm (11.4 feet) long. The mouth has a rigid ring around it, as a koinobori is a type of windsock and the wind flows through the open mouth, ausing the banner to flutter in the wind and look as though it is swimming in the air.  They are traditionally hung outside in Japan to celebrate Boy's Day. 
Some marks due to age but in very good condition, see photos.
A hard to find, vintage item
Would make a fabulous display item for interior design, see last photo for a couple of display options
Made in Japan

Condition: 
Very good - some very minor marks

Measurements:
Approximately 348cm (11.4 feet) long. A photo shows a woman standing at the mouth end  to give you a rough size reference
