The Thibetan ravine deer before 1869

"The Thibetan Ravine Deer" is a scientific illustration of the head and antlers of a _Picrocapra picticaudata_ by artist Arthur Lucas. The drawing, likely created before 1869, features a detailed depiction of the animal's white fur and long, slender horns, providing a glimpse into the natural world of the Tibetan Plateau. This illustration likely served as a scientific documentation of the species, as it was accompanied by a description of the animal's characteristics and habitat.
