Group of trees 

Franz Kobell, a German artist known for his landscape drawings, created this pen and ink drawing titled "Group of Trees." The artwork features a cluster of trees, depicted with a focus on the intricate details of their branches and leaves. The minimalist background suggests a serene, natural setting. The drawing likely dates from the late 18th or early 19th century, during Kobell's prolific career. The piece is currently housed at the Städel Museum, showcasing Kobell's skill in capturing the essence of nature.
