This fascinating 1969 issue from Umm Al Qiwain features classic and modern aircraft, each boldly overprinted “APOLLO II” to commemorate the historic first Moon landing. The set includes various denominations from dirhams to riyals, showcasing a mix of vintage biplanes, pioneering monoplanes, passenger liners, and military aircraft. While originally part of a broader aviation-themed series, the overprint links the stamps directly to the Apollo 11 space triumph. Highly collectible, these issues represent both the excitement of early aviation and the global celebration of mankind’s first steps on the Moon.
