Eight lunar phases progress vertically down the center of a deep black starfield, moving from full illumination through shadow to darkness and back toward brightness. The moons display realistic surface detail and coloring, from silvery white to rust-copper tones, arranged with mathematical precision against a scattered field of white stars. 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.
