Interlocking abstract shapes in split pea green and cream form a seamless, rhythmic tessellation across a white ground, creating a hypnotic mid-century modern pattern. The organic, rounded forms interlock like puzzle pieces in a tight grid, evoking both geometric precision and the fluid, biomorphic vocabulary of 1950s artwork. 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.
