Collection of fieldnotes compiled by Dr. Marion Oettinger while conducting anthropological fieldwork in Mexico, primarily in the 1970s. Oettinger's research focused on lienzos. A lienzo, from the Spanish word for "canvas," is a sheet of cloth painted with indigenous Mesoamerican pictorial writing. This collection includes fieldnotes on nine lienzos: the Lienzos of Chalchihuapan, Malinaltepec, Petlacala, San Gabriel Etla, San Juan Cuautla, Santiago Atitlan, Santo Domingo Barrio Alto, Xochiaca, and Xoxocatlan. The fieldnotes include photographs, slides, negatives, and transparencies; photocopies from printed works and government documents; typed and handwritten notes; manuscript drafts; maps; and correspondence.
