Jean Fautrier's *Construction Rectiligne* showcases the French artist's distinctive approach to materiality, with richly textured layers of oil and pigment built up on paper laid on canvas. The work reveals Fautrier's mastery of surface, where thick, tactile applications of paint create a complex interplay of form and substance. Restrained geometric elements emerge from the densely worked composition, reflecting the tension between structure and the raw, expressive qualities of his medium.
