This book provides a wide-ranging exploration of the history and traditions surrounding common (and sometimes surprising) Christian symbols of the Advent and Lenten seasons. It also contains numerous excellent suggestions for introducing these symbols into teaching and worship. In fact, so many of these suggestions are suitable for use with all ages I think it's somewhat unfortunate that the publisher chose to use "For Children" so prominently in the title, as this may unnecessarily limit the perception of how broadly useful it really is. It's worth noting that the book is written from a Catholic perspective, but again, much of the content is generally relevant across Christian traditions (I'm Methodist, myself).
In all, a fine book for those interested in learning more about how "that" came to be connected to these religious celebrations.
