A vibrant composition of interlocking geometric forms, this work showcases Delaunay's signature use of bold, contrasting colors arranged in rhythmic, repeating arcs and circles. Executed in gouache pochoir, the piece pulses with dynamic movement, embodying the artist's lifelong exploration of simultaneous color contrasts rooted in Orphism. Published in its original paper sleeve, *Rythme sans fin* reflects Delaunay's seamless fusion of fine art and design, suggesting an endless, cyclical energy without beginning or end.
