Concentric arcs in orange, periwinkle blue, pale mauve, sage green, and butter yellow stack toward the center in a bold geometric composition. Small triangular shapes peek from the corners, adding playful asymmetry to this mid-century modern interpretation of the rainbow. 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.
