A yellow tennis ball floats at the center of a geometric composition framed by coral-red triangles pointing inward from all sides, creating a dynamic sense of motion and focus. The palette of warm coral, cream, yellow, and deep navy blue is rendered in flat, bold shapes with subtle texture, evoking a vintage modernist sensibility. 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.
