This is a black and white photograph of a fascinating machine shop.  There are what appear to me to be gears and pulleys on the ceiling and tables full of machinery.  I have no idea what they all do or make but it is almost a piece of art with the big round gears (correct me if I don't know what I am seeing) and all of the pulleys, etc.  The image itself is 4" x 3" with a cardboard frame.  There is no information about where this picture was taken.  It has white flecks on it which I think are in the negative.  Somehow, I find it very interesting.  If you know what is going on, please let me know!
