Portraits 

This is a sketch by Thomas Eakins, a renowned American artist known for his realism and anatomical accuracy. Eakins was a master of figure drawing and his sketches often capture the human form with meticulous detail. The drawing shows two female figures in various poses, demonstrating Eakins's interest in the study of the human body and its movement. The simple lines and shading create a sense of immediacy and informality, typical of Eakins's working style.
