Dancing boy 

This delicate pencil sketch titled "Dancing Boy" was created by German artist Ernst Welker, known for his figure studies. The drawing depicts a single figure in two poses. The thin lines and subtle shading in the artwork suggest a sense of motion and dynamism, capturing a fleeting moment in the dancer's movements. It is a testament to Welker's mastery of capturing the human form through swift and precise lines. "Dancing Boy" is currently housed in the renowned Städel Museum in Frankfurt, Germany.
