Untitled - no. 817B 

"Untitled - no. 817B" is an abstract watercolor painting by German artist Hans Richter, a prominent figure in the Dada and Constructivist movements. This work, created sometime between 1888 and 1976, exemplifies his exploration of geometric forms, color, and composition. The painting features overlapping shapes, lines, and brushstrokes in shades of blue, gray, and black, creating a dynamic and energetic visual field. The bold use of color and the intricate interplay of lines contribute to the painting's abstract and non-representational nature, characteristic of Richter's artistic approach.
