Clint,
Thought I'd chime in since I really like pretty much all items Brooksie related. In my experience the older prints have smaller borders, but like stated previously these were made in all different sizes. I have a few different sizes myself as well as the print giveaway for "Thanks Brooks Day" which is a smaller version.
I think an original Rockwell would be out of most individuals price range unless you have several million to spend. I settled for a decent copy.
