A geometric grid of nested concentric rings in white radiates outward from squared centers, arranged in a 3 by 3 formation across a solid black ground. The hypnotic pattern evokes mid-century modern artwork with its clean lines, rhythmic repetition, and high-contrast palette that creates a sense of movement and optical depth. 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.
