Four black cats with cheerful expressions wear cozy knit sweaters decorated with festive patterns, arranged in a 2x2 grid against a warm cream background. Each cat strikes a playful pose with raised paws and curved tails, rendered in a charming vintage illustration style with hand-drawn details and folk art sensibilities. 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.
