Two sleek black cats with curved tails and pointed ears reach upward among floating starburst and needle-like atomic symbols against a soft sage green ground. The composition balances whimsy with mid-century modern geometry, rendered in bold black silhouettes that capture both feline elegance and retro-futuristic charm. 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.
