Two standing cows 

This drawing of two standing cows by Friedrich Wilhelm Hirt is an example of animal studies, a popular genre in art history. The artist captures the cows' forms with a loose yet expressive line, conveying their anatomy and movement. The simple composition and the brown chalk on a cream-colored paper contribute to the drawing's sense of immediacy, as if the artist was making a quick study from life. The work is currently located at the Städel Museum.
