It looks like LIFE is a special edition magazine on To Kill a Mockingbird. Here’s an intro regarding the origins of the book.

There’s something to be said for book-origin stories. They make the impersonal personal. Somehow individuals create which other individuals then read. In the meantime, the books transform thanks to the herald of society and they become commodities. Yet, they still contain ideas and meanings, almost as if houses exist to bundle up minds and hearts and send them off to strangers for cherishing.
