NASA - Neil Armstrong Apollo 11, July 21, 1969. Buzz Aldrin greeting the American flag. Period chromogenic print on " A Kodak Paper" paper . Image: 24 .3 x 19.2 cmSheet : 25.5 x 20.3 cmThis photograph has become one of the most iconic images of the conquest of space. The American flag, which seems to be unfurled by the wind, is actually held upright with a stick. The appearance of the flag and the absence of wind on the surface of the Moon fuelled revisionist theories on the Apollo 11 mission.
