Once you get your sign, you register it, you get your keyword and then you write your keyword on the sign. Below where you write your keyword there is space for "Info". What should you put in there? What could you put in there? Your choice. Be Creative. Sell sell sell!! Phone number might help. Key points about your car might help - ie Year, Number of Miles etc. For home maybe - Year Built - or square footage. Take a look at the pic below to see the space I'm talking about:
If you put a cool quote in the info space then share it with others. I like - 'Go Boldly' or 'Choose Wisely".
