A bright yellow tennis ball floats across a geometric composition of sage green and cream triangles, its curved white seams catching light against layered color blocks. The minimalist mid-century style creates a sense of motion and play, with the ball appearing to move diagonally across the carefully divided court-inspired background. 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.
