Having researched Vivian Maier (see previous post) I stumbled across a photographer named Bruce Davidson. He has an iconic set of shots of the New York subway taken around the 1970s. Again, I really like the raw and personal feeling the shots have, some directly engaging the viewer as the subject is making eye contact. I love the street art that adds another level to the shots. Also Bruce used both colour & black and white photography.
Again I could spend hours uploading hundreds, but here are a few of my favourites.
