Olivier Mosset's *Polyurethane on Canvas* exemplifies the artist's longstanding commitment to radical abstraction and the interrogation of painting's fundamental conditions. The work engages with the material properties of polyurethane, allowing its industrial qualities to assert themselves directly on the canvas surface. True to Mosset's practice, the piece challenges conventional notions of authorship, expression, and aesthetic value within the tradition of Minimalist and Conceptual art.
