Clark Center for Japanese Art and Culture. It was confirmed in a separate bonsai forum, that the person who commissioned the scroll also set up this display.
This was the 3rd Annual competition. The scroll was brushed in Sousho, full cursive style writing, which is often the preferred style of calligraphy when displaying a bonsai with Calligraphy. My display Sensei explained that the calligraphy does not compete with the tree, compared to the formal strong brush strokes associated with Block Print style writing.
The writing of the scroll says Ka Chou Fuu Getsu. It is four character idiom for the beauties of Nature. The characters are 花 flower, 鳥 bird, 風 wind, and 月 moon. A deeper explanation of the particular design of this scroll is provided here. I love the earth tone cloth selected, and the Gold on Green Ichimonji is a perfect complement to the work. This was the first customer to have a Kokutan (Ebony) Jikusaki onto the scroll, and it sets it apart as very beautiful.
There is one point in particular with the pairing that I love is the final brush stroke of the character moon, seems to complement the branching and trunk of the tree…It makes me feel good to know that some of my large scrolls are now coming to be used with these formal toko no ma bonsai displays.
