Opwaarts kijkende naakte man c. 1840 - 1843

This drawing, titled "Opwaarts kijkende naakte man," depicts a nude male figure looking upward. Created by Dutch artist Sybrand Altmann between 1840 and 1843, this piece is a study in human anatomy and form. Altmann was known for his meticulous attention to detail, which is evident in the rendering of the figure's musculature and the subtle nuances of light and shadow. This drawing, now housed in the Rijksmuseum, provides a glimpse into Altmann's artistic process and his exploration of the human body.
