Quellnymphe (Kachelentwurf) 

"Quellnymphe (Kachelentwurf)" is a preparatory drawing by the German artist Hans Thoma (1839-1924) currently housed at the Städel Museum. The sketch depicts a woman and a child, potentially a mother and son, with the woman holding the child closely to her, suggesting a protective, nurturing bond. This is a rough sketch, with visible hatching and details, suggesting it was a preparatory drawing for a larger work. This drawing is an example of Thoma's work with themes of family and domesticity often seen in his art.
