Thank you for viewing. I purchased this several years ago and have been storing it at home. The size is approximately 40.5cm square, and the wooden frame is about 3cm thick. As you can see in the 7th photo, there is a black line. I'm unsure whether it was there from the beginning or if it appeared after I bought it, so I've marked it as having some scratches and dirt. It's a wonderful piece of art that makes you want to collect more. Thank you for your understanding regarding this used item.
