Study of trees 

This ink drawing by Belgian artist Rik Wouters depicts a dense cluster of trees. Wouters, who lived from 1882 to 1916, is known for his expressive use of line and his interest in capturing the essence of his subjects. His bold, swirling lines create a sense of energy and movement, reminiscent of Expressionism. The drawing's lack of precise detail allows for the viewer's imagination to fill in the gaps and appreciate the artist's interpretation of the natural world.
