Brass
This is part of a comeback to the olden days and also a call back to the 1980s when brass was really in. Some people really like this old rustic look and we respect them for it, even though it can be gross at times. Some things that were popular in the past belong only to the past.
People really have to look back in history and be careful about what they choose to bring back or not. History is filled with mistakes and those who do not understand it are doomed to repeat it. So the next time you buy a book on interior design make sure you really do your research.
