The frame measurements are 38 1/2" X 41"...
This was a gift when I visited Japan many times during my technical work
Thank you for contacting Mearto and I apologize for the delay. This is a large framed silk print with traditional Japanese motifs. The seal is unreadable because of the printing process. The piece dates from the 20th century. I have added links below to similar items to give you an idea of the market. The first are for retail prices and after that are hammer prices. Some are new and others are antique; pricing is generally similar. Most are smaller in dimensions and I have taken this into account in my estimate. Please let me know if I can assist further.
