A tracing made by Nicolás León on architect's paper of a cartographic and historical manuscript dating to the 16th century that is clearly related to the Coixtlahuaca Basin in Oaxaca. It has a single large place glyph and figures of native people in the center with numerous place signs, dates, a river, and images of indigenous people and Spaniards on horseback around the borders. It was probably made between 1890 and 1892.
