Five hand-drawn mackerel swim across a cream background, each rendered in bold, contrasting colors including orange, pink, black, red, and blue. The fish are depicted with loose, expressive linework and decorative pattern fills that give them a playful, vintage character. 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.
