A playful black cat peeks out from beneath a cheerful rainbow rendered in warm coral, soft yellow, dusty teal, and sage green stripes against a cream-colored ground. The composition captures a moment of whimsical hide-and-seek, with the animal's dark silhouette contrasting sweetly against the pastel arcs above, all rendered in a gentle, retro-inspired illustrative style. 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.
