Interlocking curved lines in cream and white form a rhythmic, wave-like pattern across a deep navy ground, creating an optical illusion of continuous movement. The composition evokes mid-century modernism through its geometric precision and hypnotic repetition, suggesting both retro sophistication and abstract dynamism. 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.
