Concentric quarter-circle arcs in warm earth tones and bright oranges create a bold retro rainbow, each band precisely layered from pale beige through golden yellow to tangerine. The geometric composition embodies the clean modernism of mid-century artwork, with its flat color fields and confident curves evoking optimism and timeless style. 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.
