The following photo’s are the final four of best American iconic photographs from the site http://pictureyear.blogspot.com/2009/04/why-am-i-showing-this-picture.html
Ansel Adams – Moonrise, Hernandez.
Diane Arbus – Twins
Richard Avedon – Dovima with Elephants
Dorothea Lange – Migrant Mother.
Think if I had to pick one though I’d go with the V-J Day Times Square shot. Seems a little more “uplifting” than ones above.
