Stacked concentric U-shapes and arches in black and white create a rhythmic, interlocking grid of geometric forms that pulse with optical movement. The pattern alternates between positive and negative space, building a hypnotic composition rooted in midcentury modernist principles of symmetry and repetition. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
