Issued by Paraguay to commemorate the second descent of man on the Moon (19 November 1969), this striking airmail stamp blends space exploration with the festive theme “Navidad 1969 – Era Lunar.” The design features a stylized lunar surface and Earth rising above the horizon, symbolizing humanity’s new space age achievements. Bold magenta “PARAGUAY AEREO” lettering contrasts beautifully against the dark cosmic background. The “Adicional Pro-Monumento Al Mcal. López” surcharge adds historical and postal interest. A desirable topical for both space and Christmas collectors, and a classic late-1960s Paraguay commemorative issue.
