That girl with the eyes. I'll bet that is still what a bunch of people think when they see a National Geographic magazine. I do. Apparently the magazine itself still does as well, given that picture's presence all these years later in its current marketing media.
Just as cool as that image itself, taken in 1985 by the way, is the fact that the photographer spent a ton of his life afterwards looking for that girl. He found her years later, looking more like a world weary, war weary refugee, but her eyes were still there.
My favorite magazine. Compelling imagery being the leading reason.
