The four drawings with animals
"Ospreys" - a drawing made with a charcoal and a white chalk on a gray wrapping paper
"Lion" - a drawing made with a charcoal and a white chalk on a gray wrapping paper
"Indian on the Horseback" - a pencil and a white chalk on a gray paper.
Indian on the horseback is the sculpture of Cyrus Edwin Dallin "Appeal to the Great Spirit" from 1909.
"Buffalo" - a pencil and a white chalk on a gray paper. Unfortunately, the quality of the drawing is not good.
