Another card I sent to a patron on my route, and used the opportunity to push for a future Ice Box Card need.   This card of ‘Late Delivery’ was invented to apologize for getting a package mailed late or for missing a birthday.   My daughter liked the design of the card as a retro book look with the dark black background with minimal color and large, enhanced moon.   Most people who buy this card don’t understand how to use it, but they love the design’s appeal.
