A bright yellow tennis ball floats at the center of a geometric composition divided by cream and tan diagonal stripes, with a dark teal triangle anchoring the upper left and a forest green triangle grounding the lower right. Soft shadows fall across the ball and background, creating subtle depth within this minimalist, color-blocked arrangement that captures the essence of the sport through pure form and restrained palette. 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.
