Organic curved lines in solid black and cream interlock across a square composition, creating an abstract pattern inspired by midcentury modern artwork. The flowing forms suggest topographic lines or aerial landscapes, with rhythmic waves and rounded rectangles that feel both structured and fluid, evoking the geometric optimism of 1950s architecture. 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.
