Stacked concentric shapes in graduating shades of blue radiate outward from a dark navy center, creating a hypnotic ripple effect that suggests sound waves or water disturbances. The composition uses clean geometric curves and a cool palette ranging from pale cyan to deep indigo, evoking the rhythmic movement of ocean echoes through minimalist abstraction. 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.
