A black cat playfully climbs a crescent moon while another stretches atop a smiling sun, both rendered in warm golden yellow against a soft beige ground. The minimalist silhouettes and closed-eyed faces create a whimsical, peaceful mood that celebrates the duality of day and night. 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.
