The mail mixup idea is based on personal experience. The New Era sends its cartoonists a copy of the magazine when one of their cartoons is published. One time instead of a magazine, like the invoice said, they accidentally sent me a copy of the Book of Mormon. I called them and asked if I should return it, because somewhere out there is a person who requested a Book of Mormon and instead got a New Era. They told me not to worry about it; I could keep the copy of the Book of Mormon... or give it away!
I've been cartooning since I was a teenager, and have been published in magazines ranging from AASHTO Quarterly to the LDS Church magazines and several other periodicals, trade publications and newsletters.
