Ilya Bolotowsky's *Ellipse with Yellows* (1977) is an acrylic on canvas that showcases the artist's signature Neoplasticist approach, confining bold geometric forms within an elliptical composition. Vibrant yellow tones interact with other primary hues and stark lines, reflecting Bolotowsky's lifelong dedication to the principles of Mondrian-influenced abstraction. The work exemplifies his masterful balance of color, rhythm, and structure within a non-rectangular format he frequently explored in his later career.
