A bright yellow tennis ball sits at the center of a geometric composition made from overlapping triangles in deep blue, forest green, and cream, creating a dynamic sense of movement around the sport's central subject. The retro graphic style employs clean lines and flat color blocking with subtle texture, evoking mid-century sports poster artwork while the word "TENNIS" anchors the bottom in bold typography. 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.
