Crystal-clear turquoise water reveals a rippled sandy seafloor below, with sunlight refracting across the undulating surface in patterns of light and shadow. The composition moves from deep blue at the top through translucent aquamarine to bright sand, capturing the serene clarity and depth of shallow tropical waters. 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.
