Map Addressed Christmas Card

When a steel worker wanted to send a holiday card to a coworker but forgot his address, he tried his luck and drew the map of his coworker's home. He sketched the map onto the front of the envelope from the map his coworker had shown him, and where he had pointed where his home was.
