Mystery Giver

For several months now, our household has been receiving Highlights for Children, the famous kids'-interest magazine with games, jokes, stories, and of course, the continuing adventures of Goofus and Gallant that I remember so well from my own childhood (there were always copies in the waiting room of Dr. Richard O. Strand, DDS). We didn't order it, however, and we've never been able to thank the buyer of the subscription.

All we've been able to establish, detective-wise, is that the giver wasn't quite sure how to spell one of our children's names (C became K).

Can you help?
