A buffalo 

"A Buffalo" is a sketch by German artist Johann Nepomuk Rauch, known for his portraits and historical paintings. Rauch's "A Buffalo" displays a single buffalo in profile, its head lowered, with its body outlined against a simple, light background. The sketch is a study in form and anatomy, with the artist's attention to detail evident in the animal's musculature and the way its hide catches the light. This artwork is a testament to the artist's keen observation and skilled hand, giving a glimpse into Rauch's artistic process and the power of a single, focused subject.
