I've mentioned before that i have a particularly talented sumi-e artist that does my shikishi scrolls for tokonoma display. she was trained in japan and only places her mark on the
side, right or left, depending on where she sees the movement or flow of her work going. This is particularly helpful in setting up the display. The mark itself can be top or bottom depending on the placement of the subject.
I agree with the others that the scroll displayed is NOT Japanese. And yes I could see something like this used in a display singularly during a tea ceremony where the script discribes a theme and does not have to work with other items.
The crow I have used as an example, is often placed in my tokonoma with a leafless deciduous tree bonsai. Occasionally I might use
a suiseki of snow capped mountains along with the display but over time I'm learning less is more in the effort to make it totally an understatement.
I don't consider myself the judge of a good display, rather seeing the reaction of the quest to see how well they "get it".
Surprisingly, as hard as I try to get books and instruction from Japan on bonsai display, I have found the book by UK artist Paul Goff, entitled methods of bonsai display, to have helped me the most in learning.
