Kōrin's Painting Style (Kōrin gashiki)

Two gray book covers side by side. Both covers have a similar design and are rectangular. They appear to be made of a worn, aged material. A white label with black text is at the top of each cover. The text is too small to read. There is a red line on the right edge of each cover, and a red rectangle pattern on the right side. The left cover has some black writing on the left side. The covers have some darker spots and lines. The background is black around the covers.
