Woodblock print is a part of a four seasons series by Japanese artist Imao Keninen called "Keinen Kacho Gafu." This is Keinen's most famous series with this particular print coming from the winter album done around the late 1800s. There is some discoloration on the print due to age and wear. 
 
The information on the back of the work says that it is a painting, but after evaluation, we believe this to be a woodblock print.
