A small butterfly sits at the center of concentric, symmetrical waves that ripple outward in alternating bands of black, white, and gray. The geometric pattern creates a hypnotic op-art effect with a distinctly retro sensibility, evoking the visual language of 1970s artwork through its bold graphic simplicity and high-contrast palette. 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.
