Zwei weibliche Akte, kauernd und kniend 

"Zwei weibliche Akte, kauernd und kniend" is a charcoal drawing by Wilhelm Trübner, a German artist known for his academic style and figure studies. This work features two nude female figures, positioned in dynamic poses, one crouching and the other kneeling. The use of charcoal creates a sense of immediacy and allows for subtle variations in shading, emphasizing the figures' form and anatomy. This drawing exemplifies Trübner's mastery of figurative representation and his interest in capturing the human form in a naturalistic manner. The piece is currently housed in the Städel Museum, Germany.
