Some of the photo's are more mundane than riveting (like Marilyn Monroe's skirt billowing around her in Manhattan), but most are galvanizing moments of great importance, frozen in time.I disagree with the platitude that a picture is worth one thousand words. Many are not, but these are worth many more. The pictures speak for themselves, but are accompanied by a descent amount of text.
