Geometric calligraphy written in CRH Shorthand

A vertical composition of black strokes on a white background, formed using a broadnib calligraphy pen. Short, thick horizontal strokes are scattered throughout, not aligned in any particular way, as are some circles and loops. Some of these elements are free-floating, but many of them are joined together with long, thin vertical and almost-vertical diagonal lines. More such thin lines stand on their own to fill out the piece with a steady up-and-down texture.
