A yellow tennis ball with a white curved stripe overlaps a dark blue sphere against a geometric composition of green and cream triangles arranged in a pinwheel pattern. The layered, textured illustration uses a restrained mid-century modern palette and clean lines to capture the essence of lawn tennis with graphic elegance. 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.
