Black square and a white tube-shaped 

This black and white drawing, by Russian avant-garde artist Kazimir Malevich, features a simple geometric composition of a black square and a white tube-shaped form. The work is likely a study for Malevich's later Suprematist compositions, known for their abstract shapes and exploration of pure form and color. Malevich's work, part of the Suprematist movement, rejected representational art in favor of non-objective art, using geometric forms to create a new visual language.
