Two squares 

"Two Squares" is a sketch by the Russian artist Kazimir Malevich, a key figure in the Suprematist movement. Malevich's work is characterized by its geometric simplicity and abstract form, rejecting the traditional representation of objects and emphasizing the pure essence of color and shape. This sketch demonstrates his exploration of geometric forms, setting the stage for his iconic later works like "Black Square". The use of simple lines and black and white creates a sense of minimalism and abstraction, allowing viewers to focus on the pure forms themselves.
