A tennis ball rendered in yellow sits at the center of a geometric composition framed by four olive green triangles pointing inward from the corners of a cream background. Layered circles in gold, navy, and white create depth and movement around the ball, suggesting the energy and precision of the sport, while the word "LONDON" anchors the piece in a clean, understated typeface below. 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.
