What is it about rust? The rich color? The texture? The history of the piece?
All of the above... I love rust! While in NH I took quite a few pictures of rusty equipment as well as collected rusty 'bits'. This pic is part of the front end on a Model A 'doodlebug'. I hope you can use in your work. If you need a higher resolution just drop me a line and I will send it to you. Please include your email addy in your post.
