That's one small step?
"That's one small step for man, one giant leap for mankind", as uttered by Neil Armstrong on stepping on the moon on July 20, 1969.
This image at first glance looks like any normal shot with a woman walking down some steps, but on second glance she is a giant compared to the people on the left. A giant woman taking a giant leap in a bill board poster? Hence the Armstrong quote.
Another "decisive moment"?
