robert frank's "the americans"

I really enjoyed seeing the Robert Frank exhibit at the National Gallery. In my art and studies, I am interested in American identity and iconography and that is what I liked most about Frank's work. He is a foreigner, so in coming to America and creating this body of work, one might expect for it to be covered in commentary and the photographic "hand of the artist." I don't think it's like that at all. I feel as though Frank truly captured the essence of the American spirit and let the photos offer commentary on themselves, not the other way around, making for some very effective photographs.
