The wife picked these up for her and I while we were in D.C.
On Saturday she was at a store picking up some greeting cards and had this button on her purse. The clerk saw it, smiled, and asked the wife where she got it as she wanted them for herself and her husband. She seemed to be disappointed when the wife said D.C.
The person behind my wife, listening to the conversation, asked to see the button. After seeing it he wanted the buttons for himself and his friends.
Made my day!
