Don't lose this card!Logo Design Contest

Don't lose this card!

I am in need of a logo that would go on a postcard that would say: "Don't lose this card!"

I don't care what colors are used as long as they are bold

I am trying to encourage my clients to physically hold on to the card to ensure a longer shelf-life as well as have them understand that there is an incredible $ value (which will be explained in full on the back side of the postcard). I also want my clients to request cards from me to give out to friends, family and co-workers to encourage them to use my services as well. I need the logo to be bold, "in your face" and with a lot of attitude - you may want to consider a caricature or money symbols but you are not bound to those ideas. I'd rather not say what my business is because I don't want to influence designers' creativity but if it helps, I will be happy to share this a little later in the contest. The sky is the limit. Have fun and I promise to give feedback. By the way, this is my second contest in a month - my first contest went exceptionally well and I really tried to honor everyone's efforts.
