I’ve added to my collection of books about mail! Mr. Zip and the U.S. Mail is another book designed to teach kids about the U.S. postal system. Someone posted it on Instagram last year and I found it on Amazon through a used book dealer for $5. It’s an old school library book in excellent condition. I’m no reading level expert, but it feels like it was written for a younger audience than this book that I wrote about a few years ago. 
It was written in 1964 by Jene Barr and it follows Mr. Zip, a letter carrier, through the mail delivery system. (I really wish we still had small letter boxes on posts like the one next to the traditional blue box! 
Can you still send a baby chick in the mail? 
Jimmy is mailing a thank you note to his Uncle Mike for sending him a stamp book. 
It’s so funny that we think of mail as “slow” nowadays when it was considered fast back then. But this is a pretty fun predictor: someday maybe we’ll be sending chocolates and letters to our friends on the moon!
P.S. Another old book about letter writing…this one is for grown-ups!
I was at the PO last week and the person in front of me was picking up a box of chicks.
That’s a neat book.
