The listing, The Festivals of the Twelve Months Hanabusa Itcho Art Print and Key Full Color has ended.
The Festivals of the Twelve Months, from the The Boston Museum of Fine Arts. The first screen shows festivals from January through June and the second from July through December.
The name is "The Festivals of the Twelve Months" and it is by Hanabusa Itcho, who lived from 1652 - 1724. He used the name Taga Choko while painting in the Kano school. This byobu could be of the Kano school, (master Kano Yasunobu) but I think it is a later evolution of Hanabusa's technique. He was a forerunner of the "floating world" school. The original is in the Boston Museum of Fine Arts, although it has not been regularly exhibited and is not now on exhibit.
He was 58 when he took the name Itcho instead of Choko, when he was returning to Edo from exile, where he lived for 15 more years.

This reproduction of the screens, printed back to back instead of as two freestanding screens. This was done on paperboard by Horizon magazine and came with a small key to the scenes on the screens. There are no copyrights or years printed anywhere but I would estimate 50s-60s.
