We recently came across this great flickr account Elisha Cook Jr.
aka Allan Ludwig, a 73 year photographer based in New York. Recently he has been photographing the Spring Street project curated by Woostercollective.

What we like about his collection of images over the thousands of other Spring Street images on flickr is his dedication to capturing all the small marks, doodles, you know the sorts of things that most people would have missed as they were focusing on alll the larger pieces of work. Take some time out and have a look at his pictures.
