A bright yellow tennis ball with white curved seams floats across a diagonal cream stripe that cuts through a rich green ground, casting a dark navy shadow beneath it. The composition uses bold geometric shapes and a limited color palette to capture the energy of sport with graphic simplicity and clean, modernist lines. 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.
