As noted above, I love the "DVF heritage print chainlink" in black and white. You can google that term to see what it looks like. I like the bold pattern, the simplicity, and it being symbolic of connecting buyers and sellers -- classic, timeless, rock solid business person.

I like the DVF/Diane von Furstenberg logo.
I like the Kate Spade logo - maybe with a house at the top, my name, and REALTOR underneath. www,katespade.com
The Tory Burch logo is nice. I can get business cards and folders with gold leaf if I go with gold for the color of a log, for example. www.toryburch.com
