A fossilized ammonite spiral dominates this close-up composition, its pale grey-blue shell contrasting sharply against surrounding darker brown and rust-toned specimens. The layered, chambered geometry of the central shell echoes outward in concentric patterns, creating a mesmerizing sense of depth and natural mathematical precision. 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.
