A rainbow arc rises across a deep teal background in bold, concentric bands of orange, pink, yellow, and green. The composition balances geometric simplicity with a warm, optimistic energy, rendered in flat color with clean edges that evoke mid-century modernist artwork sensibilities. 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.
