Colorful starburst shapes in blue, pink, orange, yellow, and green radiate across a pale cream grid in this geometric pattern inspired by mid-century atomic artwork. The stars repeat in a rhythmic, orderly arrangement that evokes the optimistic spirit of 1950s modernism, with clean lines and balanced color blocking creating a sense of cheerful, organized energy. 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.
