Stacked horizontal bands of black and gray semicircles and curved segments create a rhythmic, interlocking pattern across a white ground, evoking pebbles or abstract geological forms. The composition balances solid black shapes against textured gray tones, producing a meditative geometric composition rooted in mid-century modernist aesthetics. 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.
