Sign Talk A Universal Signal Code, Without Apparatus, for Use in the Army, the Navy, Camping, Hunting, and Daily Life

"Sign Talk" by Ernest Thompson Seton is a manual about a universal signal code, blending practical instruction with cultural observations. Rooted in the gesture language of the Cheyenne Indians and other sources, Seton presents a system designed for communication across linguistic barriers in various settings like the military, outdoor adventures, and daily interactions. Opening with the author's introduction to Indigenous sign language, the book evolves into a guide featuring around 1,725 illustrated signs meant to promote clear, non-verbal exchange and preserve the heritage of Native American gesture communication.
