Group of trees 

Franz Kobell, a German artist known for his landscape drawings and watercolors, created a simple but beautiful depiction of a group of trees reflected in a body of water. The work is done in a loose and expressive style with a focus on capturing the natural forms and textures of the scene. This drawing, housed at the Städel Museum, is a testament to Kobell's mastery of depicting the beauty of nature with simple strokes and brushwork.
