A stylized astronaut in a white suit floats against a red background populated with geometric buildings, desert landscapes, and abstract machinery suggesting an alien settlement. Bold yellow, blue, and orange shapes overlap in a rhythmic composition that captures the optimism of mid-century space exploration while depicting a human presence on the Martian surface. 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.
