Great to see some non Western / European art.
https://en.m.wikipedia.org/wiki/Ledger_art
An increasing supply of ledger books and other paper came from traders, government agents, missionaries, and military officers.[7] With these came pencils, ink fountain pens, crayons, and watercolor paints.[8][9] These new tools allowed for greater detail and experimentation than the earlier tools, such as bone or wood styli dipped in mineral pigments, had. The compact ledger books and pencils were highly portable, making them ideal for nomadic lifestyles.[10]
