Undulating curves and concentric arcs in navy, coral, chartreuse, and pink swirl across a turquoise ground, creating a hypnotic mid-century modern composition. Soft organic shapes interlock and flow outward from partial circles at the edges, evoking 1970s psychedelic energy without sharp angles or aggression. 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.
