A grid of colorful squares in red, yellow, green, blue, and pink is layered with bold half-circles in contrasting hues, creating a rhythmic pattern of overlapping geometric forms. The composition balances rigid rectangular divisions with the soft curves of the circles, evoking mid-century modernist artwork principles with confident, primary-colored blocks that feel both playful and structured. 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.
