None of Your Business Cards
"Want to have some fun at your next business meeting? Bring along the latest creation from NYC’s MausethDesign. Their self-promo, None of Your Business Cards, are an ingenious set of faux business cards, which upon close inspection contain fake names and numbers and a special hidden message: never call me again. In addition to meetings, None of Your Business Cards have been known to work well at: clubs, bars, lounges, coffee shops, class reunions, Chinese restaurants and traffic stops."
