Ein gebeugter und ein gestreckter Arm 

This drawing, "Ein gebeugter und ein gestreckter Arm," by Victor Müller, is a study of human anatomy. It depicts a bent and a straightened arm. The artist, a German painter, has used graphite to delicately outline the muscles and tendons of the arms, creating a sense of realism. This work is a fine example of the meticulous study of the human form that was common in the 19th century, and it showcases the artist's keen observation and understanding of anatomy. The drawing is now in the Städel Museum, a renowned art institution in Frankfurt am Main.
