I'm a big fan of Irving Penn as well, and agree with much of what the above poster stated. I will add, I think his still life work is incredible. The gutter trash... there are some cigarette butts... I mean... who else could have made such incredible images of something as inocuous and ignored as a cigarette butt found in the gutter?
Not to mention the skulls!
Edited to add... sorry, didn't discuss this photograph! Looks like those skulls, huh? Thanks for posting, Jim!
