This appears to be an early to mid 20th century image on mulberry paper. From the images it is challenging to discern if the image was hand painted with sumi ink, brush and wash or if it is a print of an original. I am not able to decipher the characters on this for you. The estimate is based on being an unknown artist and original painting and utilizes actual recent past recorded auction sales of comparables. This does not serve as an authentication of the work being an original painting.
