Drafting brush 

This elegant, minimalist ink painting by Zenkei Shibayama features a single feather with its quill wrapped in a simple binding. The feather is depicted with delicate, precise brushstrokes, creating a sense of tranquility and stillness. The addition of the calligraphy above the feather adds another layer of meaning to the artwork, hinting at a deeper reflection on the nature of writing and creation. The spare composition and simplified forms are characteristic of the Japanese Sumi-e painting style, which emphasizes economy of line and the evocative power of suggestive imagery.
