Cheerful cartoon planets with smiling faces sit clustered across a soft blue and white checkerboard ground, each rendered in mint green with rosy cheeks and tiny crowned hats. The pattern repeats in a playful, whimsical rhythm that evokes vintage children's illustration and mid-century optimism. 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.
