SUBWAYblogger isn’t the only crazy one using the subway as a center subject matter. Cully from the blog A Child of Atom sketches the people he sees on the NYC Subway. His stuff is really cool. This is one of his most recent sketches.
I thought it was hard to type a complete posting in the time it takes to get from point A to point B. Yet somehow he manages to do an awesome sketch.
A full portfolio of his work is available on Flickr.
