A bright yellow tennis ball floats at the center of a geometric composition, layered with olive, navy, and cream circles that suggest motion and depth. Four rust-orange triangles frame the composition in a modernist arrangement against a warm cream background, creating a sense of dynamic balance and retro sporting energy. 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.
